About this product
The MQ-9 gas sensor module detects carbon monoxide, methane and LPG. It provides both analog and digital outputs, and an onboard potentiometer lets you set the alarm threshold of the digital output. It suits gas-leak detection and safety monitoring projects built around microcontrollers such as Arduino.

Frequently asked questions
What is the price of MQ-9 Carbon Monoxide Gas Sensor Module in Egypt?
MQ-9 Carbon Monoxide Gas Sensor Module currently costs 80 EGP in Egypt.
Where can I buy MQ-9 Carbon Monoxide Gas Sensor Module in Egypt?
MQ-9 Carbon Monoxide Gas Sensor Module is available from Most Electronics. Compare the offers above to find the best price.
How do I connect it to an Arduino?
Connect VCC and GND to the power pins (check the voltage printed on your module, typically 5 V), then read the analog output on an analog pin such as A0. The digital output can be used for a simple threshold alarm.
Does the sensor need a warm-up time?
Yes. MQ-series sensors need a preheating period after power-on before their readings become stable, so allow the module to run before calibrating or relying on the readings.
