TSENSE: CO2

CO2 Sensor with Temperature, RH & Display

TSENSE is an advanced and versatile 3 in 1 transmitter. Designed for installation in the air
conditioned zone, it measures CO2 concentration, temperature and humidity in the ambient air.
The data is transmitted to a BMS system or stand-alone controller using a standard output (analog
or relay) or via BACnet™ or Modbus communication protocols. TSENSE combines all the necessary
elements for effective climate control in commercial office buildings, hospitals, hotels, schools
and other facilities, allowing for a comfortable and healthy environment for the occupants. It is
flexible in design and is suitable for use in many different energy efficient ventilation strategies.
The TSENSE incorporates a NDIR (non-dispersive infrared) technology and complies with ASHRAE

189.1. (TSENSE units can be configured in the field using the touch screen display or by UIP5
Software via a USB to Serial adapter cable with a 3.5 mm audio jack).
