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
-Stand-by mode



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

Power supply
5.5 to 12.0 V DC
Power Consumtion ~250μA (1 measurement/hour)

~50μA in sleep
~60 mA average during active measurement sequence (~12s)
< 150 mA peak current (averaged during IR lamp ON, 100 msec)
< 250 mA peak power (during IR lamp start-up, the first 50 msec)
for maximum operating time (if powered by batteries), choose batteries that can
deliver 250mA pulses without large voltage drops (for example batteries recommended for cameras)
