MG-811 Carbon Dioxide Co2 Sensor Module เซ็นเซอร์วัดก๊าซคาร์บอนไดออกไซด์ Co2 PCB สีน้ำเงิน

Carbon dioxide detection sensor module (with analog signal output, TTL level signal, temperature compensation output),
working voltage: DC 6V
Features:
1. With signal output indication;
2. Dual signal output (analog output and TTL electrical output)
3. TTL output valid signal is low level . (The signal light is on when the output is low, and it can be directly connected to the microcontroller)               
4. The analog output is 0-2V;
5. It has high sensitivity and good selectivity to carbon dioxide;

The sensor has good sensitivity and selectivity to CO2, and is less affected by changes in temperature and humidity. Has good stability and reproducibility. Mainly used in air quality control system fermentation process control greenhouse CO2 concentration detection structure and test circuit sensor characteristics
