MG811 Module - Air Carbon Dioxide Sensor CO2

MG811 Module, Air Carbon Dioxide Sensor CO2

The MG811 Air Carbon Dioxide Sensor is a sensor that detects the amount of carbon dioxide (CO2) in the air. It has high sensitivity and great selectivity to carbon dioxide. It is a CO detection device used in the home environment, underground storage, tunnel. It is suitable for detecting carbon dioxide concentration.

MG811 Module Features:

• Signal Output Instruction
• Dual Signal Output (Analog Output and TTL Level Output)
• TTL Output Valid Signal Low. (Low signal when the output light can be directly connected to the microcontroller.)
• 30~50mV Analog Output Voltage (The higher the voltage, the higher the concentration.)
• High Sensitivity and Selectivity to Carbon Dioxide
• Long Lasting and Reliable Stability
• Quick Response Feature
• Simple Driver Circuit 

MG811 Module Technical Features:

• Size: 22x35x29mm
• Main chip: LM393, Carbon Dioxide Gas Detection Probe
