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
