MG811 Carbon Dioxide Gas Sensor Module

Carbon Dioxide  (C02) Gas sensor Module

The CO2 sensor are very sensitive about CO2 rather than alcohol and CO as they are based on solid electrolyte battery principle. When introduced to a CO2 environment, an electrode reaction happens between both the positive and negative electrode and electromotive force is generated between the sensor sensitive electrode and reference electrode. This reaction makes the output voltage to fluctuate. This fluctuating voltage is used as an alarm to detect CO2.

  • Main chip : Carbon Dioxide gas Sensor MG811 
  • Working voltage : DC 5 - 6 volts
  • CO2 tested concentration range : 0 to 10000ppm
  • Can be interfaced directly to Arduino as well as Raspberry Pi

Features of MG811 C02 Sensor Module

  • It having a signal output instruction; 
  • Dual signal output (analog output, and TTL level output); 
  • TTL output valid signal is low. (Low-level signal when the output light can be directly connected to the microcontroller) 
  • Analog output (0 ~ 2V/0-4V) voltage output selectable default hair 0-2V; 
  • Carbon dioxide has a high sensitivity and good selectivity; 
  • With a long life and reliable stability; 
  • Rapid response and recovery characteristics; 
  • The probe can plug design for easy testing.

Applications of MG811 C02 Sensor Module

  • Suitable for detecting the concentration of carbon dioxide
