MG811 (Co2) Carbon Dioxide Gas Sensor

Carbon dioxide detection sensor module (with analog signal output, TTL level signal, temperature compensation output.

Specifications:

• Operating voltage: DC 6V.
• Dual signal output (analog output and TTL level output).
• The valid TTL output signal is low. (When the output is low, the signal light is on, it can be connected directly to the microcontroller).
• Analog output 0-2 V.
• High sensitivity and good selectivity to carbon dioxide. concentrations from 350 to 10000ppm (parts per million).
• The main chip: LM393, carbon dioxide gas sensor probe

Package Included:

• 1Pc * MG811 (Co2) Carbon Dioxide Gas Sensor
