New WiFi communicating CO2 transmitter delivers energy savings in buildings

    DELTA, BC, June 17 /CNW/ - AirTest Technologies (TSXV: AAT) announced
today that it has introduced the TR9294-WF wireless CO(2) and temperature
sensor that significantly reduces the cost of installation of this energy
savings control technology into existing buildings. This proprietary sensor
technology is designed to communicate using WiFi (IEEE 802.11), currently the
most widespread, inexpensive and robust wireless network available for homes
and buildings.
    The new wall mounted wireless CO(2) sensor is designed to take advantage
of existing WiFi voice/data networks that are already installed in millions of
office buildings, health facilities, university campuses, hospitality venues
and public assembly areas worldwide. According to George Graham, President of
AirTest "The cost of wiring CO(2) sensors into buildings is often many times
the cost of the sensor. By tapping into this already widely deployed method of
wireless communication, the total installed cost of our sensor system can be
reduced by 50 to 70% resulting in energy paybacks that will occur in a matter
of months for many types of buildings."
    The signal from the sensor can be directed over a local network to a
building control system and/or over the Internet to any remote monitoring/data
collection location. It can be used for temporary or permanent deployment. The
TR9294-WF is also very secure and supports major wireless encryption protocols
(WEP128 and WPA2=PSK) and will support DHCP or a static IP address. The device
is self-calibrating and maintenance free. The cost and nuisance of battery
replacement is eliminated because the device uses 24VAC low-voltage power,
which is readily available throughout most buildings. "This sensor offers
simple installation and immediate activation" said Graham, "Attach the
TR9294-WF to the wall, power it up and it will start communicating instantly
with the building's local wireless network to monitor and/or control both
temperature and building ventilation".
    The unit has been designed with the highly popular LEED green building
certification program in mind. This program, initiated by the US Green
Building Council, provides certification points for including CO(2)
measurement and control in new and existing buildings. As required by this
program, the TR9294-WF transmitter can provide an audible and visual indicator
of elevated levels indicating a possible malfunction of the building control
    AirTest's self-calibrating CO(2) sensors save energy in buildings by
regulating outside air ventilation based on the actual number of people in a
space. This ensures that only enough outside air is heated or cooled to meet
the immediate needs of occupants. Much of the demand for this type of sensor
is driven by the growing interest in making buildings energy efficient, an
important contribution to the creation of green and sustainable buildings.
CO(2) ventilation control can represent a simple but highly effective way for
almost all buildings to reduce energy use while ensuring good indoor air
quality for occupants.
