AirTest - Ambient Light Powered, EnOcean, CO2 Temp and RH Transmitter
The TR9277-EO from AirTest is a
wireless, CO2, Temperature and RH transmitter that is powered by indoor
ambient light, making it ideal for zero energy/minimal environmental
impact projects or applications where zero maintenance is required. The
transmitter communicates using the EnOceanŽ wireless protocol utilized
by many leading building control companies (EnOcean Profile
A5-09-04). It includes an on-board pressure sensor for automatic
correction of CO2 readings based on altitude and a background self
calibration feature that combine to ensure long term accuracy.
Provisions for an optional 3V button battery backup can power the
transmitter for 5 years if no light is present.
While there is no digital display, the current concentration can be read by by pressing a button on the side of the unit that will provide a sequenced LED flash indicating the CO2 concentration. Easily calibrated to outside air.
This product is a result of close collaboration between AirTest, with their expertise in sensor technologies, and EchoFlex Systems Inc. a leader in providing light harvesting, wireless EnOcean communicating products.
AirTest also offers a line of battery powered WiFi communicating products with BACnet gateway capability.
