Overview of this MQ9 Carbon Monoxide Gas Sensor Module
Introducing The MQ9 Carbon Monoxide Gas Sensor Module at the best price in India with Roboway. This MQ9 gas sensor detects multiple gases and specially designed to sense Carbon Monoxide (CO), Methane (CH4), and Liquefied Petroleum Gas (LPG). It helps in detecting harmful gases in homes, industries, and vehicles.
This sensor gives both analog and digital outputs for flexible usage with microcontrollers like Arduino, Raspberry Pi, etc. It is quickly detects gas presence and clears when the air is clean again and it comes with a built-in potentiometer to fine-tune the sensitivity based on the application.
Features
Detects multiple gases – It can sense CO, Methane, and LPG all in one sensor.
Analog and digital output – Module supports both output types for different kinds of projects.
Adjustable sensitivity – sensitivity can be easily adjusted using the onboard potentiometer.
Operates on 5V power – compatible with most microcontrollers like Arduino and Raspberry Pi.
Fast response and recovery time – It is quickly detects gas and resets when the gas is gone.
Built-in heater – improves accuracy by heating the sensor for better detection.
