CO2 Engine® ELG

CO2 Engine ELG is suitable for low power applications as the unit can put sleep-mode between measurements. The sensor is designed to measure and store records of environmental parameters such as CO2, RH and temperature.

Key benefits

-Low power consumption
-Internal logger
-Maintenance-free
-Stand-by mode

 

Applications

This platform is designed to be an OEM module for built-in applications in a host apparatus and suits low power applications.
