WS433-CO2 sensor utilizes CMOSens® Technology for IR detection enables carbon dioxide measurements of the
highest accuracy at a competitive price. Along with the NDIR measurement technology for detecting CO2 comes a
best-in-class humidity and temperature sensor integrated on the same sensor module. Ambient humidity and
temperature can be measured by special algorithm expertise through modelling and compensating of external heat
sources without the need of any additional components. The wireless portion is Sub-GHz technology from Texas
Instruments allows long range transmission at ultra-low power consumption. It will connect 2-way wirelessly to the
wireless co-ordinator WS433-CL to send data and receiving the configuration. It can be configured the operation
parameters like data sending interval, health check cycle...remotely from Globiots platform or via ModbusRTU software
(thru the WS433-CL). Its default data rate is 50 kbps, can be switched to 625 bps to increase the communication range.
The sensor can last up to 5 years with 2 x AA battery.
