2. Brief Introduction of Our
Group…….
 Established since 1986.
 Vender for DRDO since 1988.
 Intelligent & qualified team of engineers.
 Professional work culture.
 Service network in major cities.
Our Motto
 Design & Development of custom projects.
 Introducing new concepts for conventional
working procedures.
 User friendly design concept.
 Good after sales service backup.
 Reasonable pricing.

3. CURRENT SCENARIO:
Wired Temperature Monitoring systems require wires to be run between
where the temperature is measured and where the temperature data is
stored.
Wired temperature monitoring systems are generally much more
expensive to install due to the labor involved.
Thermometers can be electronic these days, but the functionality is the
same.
The problem with thermometers is that you have to physically go and look
at the thermometer to know the temperature, and the only way to have
records is to manually record them. This is a laborious process and gets
expensive.
If you have many temperature-sensitive areas that you want to keep an
eye on.
 Manual data acquisition.
 Wired temperature sensor are analog and no more accuracy.
OUR SOLUTION:
Wireless Temperature Measurement
and Monitoring System…….

4. Product overview
The wireless temperature monitoring system
wireless transmits temperature readings from
the sensors which are placed on your Data
Center Rack to the BMS room which can be
remotely connected to PC. Temperature
readings are then displayed on PC via our user
friendly software.

9. Hardware Devices-
• Semiconductor Type Temperature
1.Temperature
Sensors
• Includes 3 temperature sensor
sensor:
• Self calibrated, recalibration is not
required
• Connected to Transmitter unit
• Is precisely accurate.
• Respond instantly.
• Semiconductor Type Humidity Sensor
2.Humidity • Connected to Transmitter unit.
sensor: • It is fully calibrated and provides digital
output.
• Low power consumption.
• Excellent long term stability.

10. • It measures temperature at 3 different points at
3.Transmitter single rack using high precision semiconductor
(Slave) unit: sensors.
• Transmits Data through high frequency channel.
• Sense 3 temperatures: Lower, Middle and Upper.
• Mounted on Data Center Racks.
• Self powered, no external power supply required.
• Life span up to 5 years.
• It is a Intermediate Trans-receiver.
4.Extender • It receives the data from transmitter unit and
unit: amplifies the data
• and transmits it to the centralized Master unit.
• Up to 16 no. slave devices can be handled by one
Extender unit.
• Operates on 230v AC supply.

11. • It collects data from all sensors.
• converts it to RS232 for further
interpretation.
5.Master unit:
• Up to16 extender devices can be
connected to one Master device.
• Equivalent to 256 Temperature sensors.
6.Data collector
• Collects data from Master unit using
COM/ USB ports.
PC: • The data is stored in the hard disc drive
for future usage.
• The PC for installation in BMS room.

12. Software Applications-
1. Live Data
• This software
application is
useful for
displaying all live
data.
• By using MODBUS
connectivity you
should access live
data of each sensor.
• Automatically
updated sensor
data.

13. 2. Export Data Tools
• This application is
useful for Exporting
Temp. Data and
Humidity Data with
desired date’s
• The Exported data
is in Excel format.
• At time 1 month
data you can export.
• Exported data will
be available in
particular assigned
folder.
• The Temperature
sensor Report and
Humidity sensor
Report are in
separate folder.

14. 3. Database
management
• This
application is
useful for
storage all
received Data.
• This database
update on Real
time clock.
• Data will store
in database
with Sequence
of received
packets.
• All the data
stored in Hard
disk.

15. 4. Hall layout
representation
• This application is
useful for
presenting room
layout.
• By moving cursor
on particular rack it
will show combine
live temperatures.
• Rack colors change
if set limits out of
range. e.g. if temp.
above set limit then
rack gets RED, if
temp. within limit
then – Blue color &
Below limit –Green
• Set limits are site
settable.
• Automatically
update live packet.

16. 5. Graphical analysis
Real time Graphical
analysis is available
for easy
interpretation.

17. Benefits of wireless temperature
system-
• RF based system.
• Low power consumption and.
• High transmission range.
• Convenient master unit and Extender unit has been designed to
mount on a ceiling or cage wall and Slave unit be portable to install
on rack.
• Monitoring: Easy, Real time and Accessible.
• Reduce energy cost.
• Reduce time taking manual readings.
• Inexpensive Wireless temperature sensor that allow you to measure
lot of points.
• Installation costs are lower because wires do not need to be run to
all the areas where temperature is monitored.
• Wireless systems are much more mobile.

18. CONCLUSION
 Significant time save during the installation
and no signal wire needed to be routed from
sensor transmitter to data collector point.
 As this brief survey of wireless transmitters
and receivers for temperature measurement
shows, many of the old limitations and
complexities of point-to-point, wired
interconnected systems no longer apply.
 The engineer, technician can use these new
devices to gain a flexibility in monitoring.
 Data can be collected and analyzed in real time
and for later using readily available.
