esp8266 with NDIR CO2 sensor on battery power : esp8266

esp8266 with NDIR CO2 sensor on battery power Hi, I am getting ready for a project where I need to create battery powered CO2 sensor. So far I have read that CO2 sensors are not a good match for battery powered projects because they need to stay always on (therefore esp8266 deep sleep mode is not an option) to be properly calibrated.
