1, three ways signal output; (analog output / serial port UCHAR output)

2, the serial port Uchar signal can be accessed microcontroller IO serial port; (TTL level 9,600, N, 8,1)

3, analog linear output 0.4-2V, the higher the concentration the higher the voltage;

4, with PWM modulation waveform output, read more convenient;

5, the module uses (NDIR) infrared technology for carbon dioxide has a good choice;

6, the module is light weight, small size, long life, good stability and so on.

This module can be widely used in HVAC and air quality monitoring, industrial process and safety monitoring, agricultural and
livestock production process monitoring, and fresh air system carbon dioxide detection.

Package included:

1 x NDIR CO2 Sensor
