Carbon dioxide sensor module CO2 sensor module MG811 

One size: 32mm X22mm X30mm L * W * H

Second, the main chip: LM393, carbon dioxide gas sensing probe

Third, the working voltage: DC 6V

Four characteristics:

1, having a signal output instruction;

2, dual signal output (analog output, and TTL level output);

3, TTL output valid signal is low. (Low-level signal when the output light can be directly connected to the microcontroller)

4, analog output 30 ~ 50mV voltage, the higher the concentration the higher the voltage;

5, carbon dioxide has a high sensitivity and good selectivity;

6, with a long life and reliable stability;

7, rapid response and recovery characteristics;

8, the probe can plug design for easy testing.

V. Application:

CO detection device for the family, the environment. Suitable for detecting the concentration of carbon dioxide, carbon dioxide gas sensors tested concentration range: 0 to 10000ppm
