## Description

Desription:Main chip: LM393, carbon dioxide gas sensing probe Working voltage: DC 6V Size: 32mm X22mm X30mm L * W * H CO2 tested concentration range: 0 to 10000ppmApplication: Suitable for detecting the concentration of carbon dioxideFeatures:1. It 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 (0 ~ 2V/0-4V) voltage output selectable default hair 0-2V; 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. Package Included:1 x MG811 CO2 Carbon Dioxide Gas Sensor ModuleHigh performance microcontroller for high stability, high reliability and low power consumption.Reverse power protection function, avoiding surge current shock.
