The Sensaphone Combination Temperature, Humidity and CO2 Sensor will measure and provide real time values to any Sensaphone that accepts a 420mA or Modbus signal. When any of the monitored conditions fall outside of the Sensaphone’s programmed high or low limits, the user will receive an alarm which displays or reads the current value.

6/5/2021· For my graduation project I am looking for a (cheap) sensor which measures CO2 and humidity and I stumbled upon the thread below via Google: In this thread someone mentions it might be possible to measure the CO2level using only an humidity sensor by using the formula: C6H12O6 (glucose) + 6 O2 => 12 H2O + 6 CO2 I am no chemic (nor a programmer), but I was wondering …

Small, discreet sensors simply stick to the wall. Measures ambient carbon dioxide (CO 2 ), temperature and relative humidity: CO 2 02550PPM (accuracy +/ 125PPM) Temperature 051ºC (accuracy +/ ºC) Humidity 0 RH (accuracy +/ 5%) Reports every 5 minutes when solarpowered or 15 minutes. when batterypowered.

6/2/2019· Anything worth measuring is worth measuring right, and to do that periodic calibration is essential. In HVAC, the primary reason to measure CO₂ is to optimize ventilation and realize energy savings. According to a recent European study, demandcontrolled ventilation (DCV) can reduce energy use by 20–50% in public buildings.
