Air Sensor CO2 – Mendel Sensors

Air Sensor CO2. Using the same iOS, Android and Web apps as the Air Sensor Lite our newest sensor now also measures CO2 (ppm). This sensor will measure: CO2 sensors do require calibration and we will provide instructions during setup on how to selfcalibrate this sensor. Each calibration process takes about 5 minutes and you only need access ...


CO2 Sensor, Detector, NDIR,

20110620· The old CO 2 sensors were calibrated using a software and the assumption of a regular background concentration of 400 to 500 ppm „ Assumption“ means that the CO 2 concentration must decrease to at least 500 ppm for 48 hours at least once every two weeks Sensor uses this minimum value as an offset Otherwise the sensor will drift from its original settings, until only incorrect readings …
