Description
The MQ4 gas sensor is a detection device designed to measure the concentration of methane (CH₄) and other combustible gases in the air. Using tin dioxide (SnO₂) technology, this sensor is sensitive to changes in gas concentration, enabling fast and accurate detection. It is particularly suitable for domestic and industrial applications, such as gas leak monitoring and plant safety.
Main Features
Type of gas detected: Methane (CH₄) and other combustible gases
Detection range: 300 to 10,000 ppm
Supply voltage: 5V
Output: Analog (variable voltage) and digital (TTL signal)
Warm-up time: About 20 seconds for accurate measurements
Applications:
Gas leak detection
Safety alarms for gas installations
Robotics and automation projects
The MQ4 sensor is a popular choice for DIY projects as well as embedded systems, thanks to its ease of use and reliability.
