Аналоговый датчик горючих газов (MQ9) для определения окиси углерода, метана и сжиженного газа Analog CO/Combustible Gas Sensor(MQ9)

Introduction
The MQ-9 Analog Gas Sensor has high sensitity to Carbon Monoxide, Methane and LPG. The sensor can be used to detect different gases containing CO and combustible gases, it is low cost and suitable for a variety of applications.

The core sensing material of MQ-9 gas sensor is SnO2, which has a lower conductivity in clean air. It makes detection by cycling high and low temperature, and detects CO when low temperature (heated by 1.5V). The sensor_s conductivity is higher along with the gas concentration rising. When temperature rises (heated by 5.0V), it detects Methane, Propane, combustible gas,etc and cleans the other gases adsorbed under low temperature.

Applications
- Domestic gas leakage detector
- Industrial gas detector
- Portable gas detector

Notice:The new version of analog sensor port pin mapping has been changed as the following two features.Please check thetips for changing sensor cable pin mapping while using the I/O Expansion shield. We will continue to update. For the inconvenience caused, please understand.
