When temperature sensors are used they often come built into a
thermostat unit or radiator actuator valve, but there are times when you may
like to fit an independent thermometer. Small temperature sensors can easily be
embedded into walls to avoid having more unsightly boxes stuck to your walls or
ceiling.
Combined with a humidity sensor, they can be used to
automatically control air conditioners or de-humidifiers, or even to
automatically open windows if a room starts to get too 'muggy'.
Waterproof temperature sensors may be used outdoors, perhaps so
that you can check whether your patio heater needs to be turned on before you
go out, for example. They can also be used in tanks to monitor water
temperature.
Tip:The placement of temperature sensors can
significantly effect their operation. Ideally they should be located away from
both doors and radiators, and somewhat down from the ceiling. If you notice
that some rooms feel hotter than others when set to the same temperature, don't
just think your mind is playing tricks on you - this is probably due to sensor
placement. You don't necessarily need to move the sensor, however, if you are
aware of the issue you can just change the temperature setting accordingly.
Common deployed control system today. The sensors and output devices (e.g., actuators, relays) used for electronic control systems are usually the same ones used on microprocessor-based systems. The distinction between electronic control systems and microprocessor-based systems is in the handling of the input signals. In an electronic control system, the analog sensor signal is amplified, and then compared to a set point or override signal through voltage or current comparison and control circuits. In a microprocessor-based system, the sensor input is converted to a digital form, where discrete instructions (algorithms) perform the process of comparison and control. Most subsystems, from VAV boxes to boilers and chillers, now have an onboard DDC system to optimize the performance of that unit. A communication protocol known as BACNet is a standard protocol that allows control units from different manufacturers to pass data to each other.
Supervisory control (building automation) system
The role of supervisory control is to control the scheduling and
interaction of all the subsystems inside a building to meet building needs with
appropriate operator input.
Supervisory control systems have many names; each used for a particular
emphasis. Among the names and their acronyms are the following:
1. BMS: Building management system
2. EMCS: Energy monitoring and control system
3. FMS: Facility management system
4. EMS: Energy management system
5. BAS: Building automation system (The most generic of
these terms)
ROOM PRESSURE MONITOR
standard
single room BACnet capable room pressure monitor for measuring low differential
pressure in critical applications. The SRPM’s backlit touchscreen LCD provides
an intuitive graphic user interface for ease of setup. The SRPM has a built-in
calibration feature and only requires zeroing when installed, significantly
reducing the cost of ownership. The SRPM monitors and alarms while providing a
digital input for a door alarm. The SRPM is a simple, cost-effective solution
which combines state-of-the-art electronics with Setra’s superior true
differential pressure sensing technology to ensure safety in critical
environments. The SRPM also incorporates two-level password protection.
Monitor Alarm Critical Rooms -
The SRPM is most user friendly room pressure monitor on the market today. It
has an intuitive touchscreen interface that allows the user to easily configure
alarm set points, passwords and audible alarming conditions. With its
bi-directional sensor, the unit can switch between protection and isolation
room modes, or be put into standby mode when the room is not in use.
On-Board Dead-Ended Pressure
Sensor - Protection and isolation rooms are designed to adhere to
strict standards in order to provide a proper barrier between the room and
reference space. Unlike a flow-through design, the SRPM utilizes an on-board
dead-ended low differential pressure sensor. This technology provides the user
with a trusted solution & peace of mind that the sensor will prevent
contaminated air from passing through it.
Save Time and Money on
Installation & Calibration - The SRPM is designed with
both the installer and end user in mind. The BACnet enabled unit can be
installed in an off-theshelf electrical box, improving the ease of installation
instead of having to use a custom electrical box that is not typically
available at the rough stage of the project. The SRPM offers push button zero
and span calibration that is easily performed by any low differential pressure
calibrator and can be calibrated in minutes.

A
light sensor may also be known as a photosensor or photodiode. It is used to
monitor the ambient light levels and report them back to your home automation
controller. This is often used in conjunction with a motion or presence sensor
to switch lights on automatically when someone enters a room - but only if they
are needed. They can also be used to ensure that security lights only operate
after dark, or make outdoor lighting come on automatically at dusk.
If
you are using a light sensor outdoors then it is obviously important to ensure
that you buy one with an appropriate weatherproof housing.
Gardening
is a wonderful way to blow off some stress and channel your creative energy in
a productive direction, but there are some aspects of gardening that are just
cumbersome and trivial. For example, remembering to keep everything watered at
the right rates.
Well,
here’s some good news: we’ve covered smart devices for your
garden before and many of them are incredible.
An egg
tray is likely the last thing on your mind that needs to be smartened up, but
it’s been done. And after reading more about it, you’ll probably arrive at the
same conclusion as me: “Dude, this is pretty clever!”
Smart Surveillance
If your
home doesn’t have a surveillance system in place, rest assured that you
can build one yourself without having to shell out tons of cash. All
you need is a few old smartphones that you no longer use.
Set them up with mobile webcam
apps like IP Webcam or any other cell phone surveillance app on the
market. Once they’re ready, you can use Webcam Watcher as a central monitoring
station for the surveillance network. If that’s too basic for you, then
you’ll probably want a dedicated smart home security device.
Motion and Occupancy Sensors
One of the most popular sensor technologies for domestic
automation systems is the motion detector. Often they will be put to multiple
uses, such as triggering a burglar alarm if movement is detected when the house
is supposed to be empty, or automatically switching lights on and off when you
enter or leave a room.
The most common type of motion detector is the 'passive infrared
sensor', or PIR. This works by detecting changes in infrared light radiation
within its field of vision. When choosing a PIR it is important to make sure
that the effective range is sufficient. Although most PIRs will easily be able
to cover a room, larger rooms, especially in open plan design buildings may
require more than one.
An occupancy or presence detector is basically the same
technology as a regular motion sensor, but with a higher resolution. You can
buy PIRs very cheaply, and they are still perfectly good for many applications
- such as burglar alarms or controlling corridor lights. But if you want a
system to be able to sense whether or not the living room is occupied, for
example, so as to control the lighting and heating automatically, a cheap
product will not be good enough. This is because they need movement to work, so
if you are sitting still on your couch reading a book, the sensor may
mistakenly send a signal to say that the room is empty. A presence or occupancy
detector is able to identify the presence of a person in the room just from
their breathing.
Tip: If you own pets then it may be a good idea
for you to look for a product with adjustable sensitivity, so that you can manually
find the right balance between operating correctly for humans, and not going
off every time your cat walks past.
Smarten Up Your Home Even More
This
list doesn’t complete without the Nest Thermostat or the August Smart
Lock, two products that I would like to recommended as the smart home
device for most all people. Check their link below for the detailed overview as I would find it difficult to explain all their features here.
Smart TVs are
another oft-recommended first device, but they’re slowly losing value
since 3D television is on the decline and smart TVs are a
security risk. But
if you’ve gotten this far and are still looking for more smart home ideas, you
may be interested in a smart doorbell, a smart home appliance, or
even a smart
toothbrush. Good luck!
Fire
is not the only risk which you need to protect your family from. Hundreds of
people die every year in the USA from Carbon Monoxide poisoning caused by
faulty household appliances.
Carbon
Monoxide is colourless, odourless, and can kill you without you even knowing
that you are being poisoned. The symptoms include headache, dizziness, and
nausea - all of which are commonly caused by a wide range of other things,
meaning that victims may think they are just feeling a bit under the weather,
go to lie down for a while, and never wake up.
Tip:The most economical
way to protect your family is to buy a combined carbon monoxide and fire alarm,
but if this is not part of a home automation system with advanced notifications
then make sure you memorize the different alarm sounds so you don't
accidentally assume that you are getting a false positive from the fire alarm
when it is actually the carbon monoxide alarm.
Flood and Leak
Sensors
Flood
or leak sensors are commonly fitted underneath
baths and kitchen sinks, or in other locations with an elevated risk of leaks.
If your plumbing does spring a leak then catching it early can save you a lot
of trouble and expense, as water damage can have a major impact on your
property.
A
good quality flood / leak detector can sense the presence of even small leaks,
and if connected to an actuator valve they can automatically shut off the water
to prevent damage and break down which can be covered in home loan/ mortgage loans and home insurances in case severe readings are detected.
Contact Sensors
Contact
sensors are used for a range of applications, the most common of which is in burglary alarms.
The sensor itself is basically just a kind of switch, which sends an electrical
signal when two surfaces make contact. They can be used to monitor whether a
door or window is open or closed.
Home
security systems often use contact sensors in window frames, to trigger an
alarm if a window is opened after the alarm has been activated. There are many
other applications too, such as:
·
Automatically
turning off the heating in a room if somebody opens a window, to save energy
waste and make it easier to cool a room down.
·
If
powered door systems are fitted you can check whether doors have been left open
and close them from a remote location.
·
Switching
on cupboard lights when you open the door.
There
are two different kinds of sensor which can detect an intruder breaking glass
to enter your building.
The
first type is installed on the window itself, limiting its usefulness for
protecting an entire property. This is also known as a 'shock sensor'
and is triggered by sudden high frequency vibrations when the glass it is attached
to breaks.
The second type is
basically a microphone tuned specifically to pick up the sound of breaking
glass. This is more useful, because a single detector can cover even a
relatively large room with many windows.

Glass Panelled Doors
Energy Use Monitors
If you want to reduce your energy usage, for either
environmental reasons, economic reasons, or both, then smart energy monitors
are a 'must have' device. They can tell you exactly how much electricity each
of your appliances, gadgets and electrical systems is using overall, and at any
given time, empowering you with all the necessary knowledge to reduce your
energy consumption. For example, you can use the information from your
monitoring device to identify which devices you own use the most energy when left
on standby, and then turn those specific devices off at the wall instead.
Microphones
In my opinion, one of the most enjoyable features that you can
build into a home automation system is voice control. Even though voice
recognition has been around for a while now, it still somehow feels futuristic
and exciting to control your household electrics and electronics with voice
commands.
Driveway Probes
A driveway probe is
embedded into the driveway outside your home, and is then able to detect when a
car is arriving or leaving. This information can be used by an automation
system to open gates when you are leaving or to open a garage door, for
example. It can also be used as part of an alarm system to begin recording if a
vehicle arrives on your driveway, and then save the recording if your alarm is
triggered within a certain period of time.
RFID Sensors
Radio Frequency Identification, or RFID, is wireless method for
an electronic chip and sensor pair to exchange data. If you put aside your
fears of government tagging and the big brother state and buy your own RFID
chips and readers you can add a wide range of features to your home automation
system.
The list may keep going on... Will keep on updating for latest gadgets for you. Send me your feedback what you would like to install at your home.
