Analog CO/Combustible gas sensor(MQ9)

10.25 €10.25

Availability: Retired

Introduction

MQ-9 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 different applications.
Sensitive 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 sensors conductivity is 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.
Applications
  • Domestic gas leakage detector
  • Industrial gas detector
  • Portable gas detector
