10 pcs MG-812 Low Power-Consumption CO2 Sensor

[shortdesc]Application:CO2 detection in air quality control, ferment process control and green house fields.Feature:Small sizes, low power-consumption, high sensitivity and good selectivity.[/shortdesc]Production Description:MG-812 is a semiconductor oxide chemical sensor that uses solid electrolyte battery principles to detect CO2.When the sensor is kept at a certain working temperature and placed in a CO2 atmosphere, an electrode reaction occurs between the positive and negative electrodes of the battery, and the output signal voltage is inversely proportional to the logarithm of the CO2 concentration. A voltage change in the test signal can detect a change in the CO2 concentration.Feature: Small sizes, low power-consumption, high sensitivity and good selectivity. Less affection by temperature and humidity. Good stability and repeatability. Application:CO2 detection in air quality control, ferment process control and green house fields.Main technical parameters: Model No.        MG812 Standard pack        Metal shell Target gas        CO2 Detection range 0~10000ppm CO2 Heater voltage VH 5.0±0.1 V Heater resistance RH 60.0±5Ω Heater current IH 85±10mA Heater consumption PH 420±50mW Working temp Tao -20～50℃ Storage temp -20～70℃ Zero EM F 200-400mV (in 400ppm CO2) Output signal  △EM F ≧20mV EMF (40ppmCO2)- EMF (1000ppmCO2)
