The Analog CO/Combustible Gas Sensor(MQ9) module is useful for gas leakage detecting, it used the sensitive material SnO2, which with lower conductivity in clean air. It make detection by method of cycle high and low temperature, and detect CO when low temperature (heated by 1.5V). The sensors conductivity is more higher along with the gas concentration rising. When high temperature (heated by 5.0V), it detects Methane, Propane, etc. combustible gas and cleans the other gases adsorbed under low temperature. MQ-9 gas sensor has high sensitivity to Carbon Monoxide, Methane and LPG. The sensor could be used to detect different gases contains CO and combustible gases, it is with low cost and suitable for different application.

MG-811 Carbon Dioxide Sensor Module for detecting Metal Oxide Sensor Carbon Dioxide (CO2), which needs to heat the tank to the specified level. With power supply This creates heat vapor and separates the CO2 from the air in general.
This sensor module has an MG-811 on-board as the sensor component. There is an on-board signal conditioning circuit for amplifying output signal and an on-board heating circuit for heating the sensor. The MG-811 is highly sensitive to CO2 and less sensitive to alcohol and CO. It could be used in air quality control, ferment process, in-door air monitoring application. The output voltage of the module falls as the concentration of the CO2 increases.
