Carbon Dioxide Sensor CO2 Sensor Carbon Dioxide Concentration Gas Sensor Module.

Product characteristics. 1. With signal output indication. 2. Two-way signal output (analog output and TTL level output). 3. The effective output signal of TTL is low level. (when the output low level signal light is on, it can be directly connected to the single-chip microcomputer). 4. Analog output 30~50mV voltage, the higher the concentration, the higher the voltage. 5. High sensitivity and good selectivity to carbon dioxide. 6. Long-term service life and reliable stability. 7. Fast response and recovery. 8. The probe can be plugged and unplugged to facilitate the test. 9. Dimensions: 32mm X22mm X30mm length * width * height. 10. Main chips: LM393, carbon dioxide gas sensing probe. 11. Operating voltage: DC 6V. Note: preheating for the first time for 24 hours at intervals of more than 6 hours. It needs to be preheated for 1-2 hours, power off for more than 72 hours and preheating for 24 hours. Product application. Carbon dioxide detection device for home and environment. Suitable for dioxidation. Carbon concentration detection, carbon dioxide gas sensor test concentration range: 0 to 10000ppm
