Gas sensors

MQ4 Gas Sensor: Detects methane (CH₄) and combustible gases with a detection range of 300 to 10,000 ppm. Powered by 5V, it offers analog and digital outputs. Ideal for gas leak detection and security applications. Convenient for electronics and DIY projects. Available in Cameroon / Africa on Composants Faciles.

MQ2 Gas Sensor: Detects LPG, Methane, i-Butane, Propane and Hydrogen with a detection range of 300 to 10,000 ppm. Powered by 5V, it offers analog and digital outputs. Ideal for gas leak detection and security applications. Convenient for electronics and DIY projects. Available in Cameroon / Africa on Easy Components.

The MQ3 gas sensor is a device designed to detect the concentration of alcohol, as well as other flammable gases such as LPG (liquefied petroleum gas), methane and hydrogen. Using a tin dioxide (SnO₂) sensing element, this sensor offers high sensitivity and fast response time, making it ideal for security and air quality monitoring applications. Available...

MQ7 gas sensor for carbon monoxide detection, ideal for Arduino projects and safety systems. Available in Cameroon at Composants Faciles in Douala.
