MQ-9 Carbon Monoxide, Methane and LPG Gas Sensor Module
Discover our MQ-9 Carbon Monoxide, Methane, and LPG Gas Sensor Module, a vital tool for detecting harmful gases in various environments. This module utilizes SnO2 as its sensitive material, ensuring precise detection even in clean air conditions.
Operating on a temperature cycling method, it detects carbon monoxide at low temperatures (heated by 1.5V), with its conductivity increasing as gas concentration rises. At higher temperatures (heated by 5.0V), it effectively detects combustible gases like methane and propane while clearing other adsorbed gases.
Ensure safety and peace of mind with our MQ-9 Gas Sensor Module, perfect for applications ranging from home safety systems to industrial and environmental monitoring.
