MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor Module

The MQ-4 is a highly sensitive gas sensor module specifically designed for detecting methane (CH4), including natural gas and compressed natural gas (CNG). This sensor module is widely used in various applications where the detection of methane gas leaks is critical for safety and environmental protection.

Utilizing a tin dioxide (SnO2) semiconductor gas sensing element, the MQ-4 sensor offers high sensitivity and fast response times to methane gas concentrations in the surrounding environment. It operates based on the principle of conductivity changes in the sensing material when exposed to target gases, allowing for reliable detection over a wide range of concentrations.

One of the key advantages of the MQ-4 sensor module is its compact size and ease of integration into different electronic systems and devices. It typically comes in a small module form factor with convenient pin headers, enabling straightforward connection to microcontrollers, development boards, and other electronic components.

The MQ-4 sensor module is particularly suitable for use in gas leak detection systems for residential, commercial, and industrial applications. It can be deployed in gas detectors, alarm systems, and safety monitoring devices to provide early warning of methane leaks, helping to prevent accidents, fires, and explosions.

Furthermore, the MQ-4 sensor module is typically equipped with onboard signal conditioning circuitry, including a built-in voltage regulator and amplifier, to ensure stable and accurate operation. It also features adjustable sensitivity and calibration capabilities, allowing users to optimize the sensor performance for specific application requirements.

In addition to its high sensitivity to methane gas, the MQ-4 sensor module may also exhibit cross-sensitivity to other combustible gases, such as propane and butane. Therefore, it is essential to consider potential interference from other gases and calibrate the sensor accordingly for reliable detection and false alarm prevention.

In summary, the MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor Module offers an effective and reliable solution for methane gas detection in various safety-critical applications. Its high sensitivity, fast response times, and ease of integration make it a valuable tool for protecting lives and property from the dangers associated with methane gas leaks.

If you want to detect methane gases with your projects, you will need sensors. If you need any data on the sensitive material then, the MQ-4 High Sensitivity Gas Methane (CNG) Detector Gas Sensor  Module is a quite good solution.

This is a simple-to-use MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor Module that can sense the presence of Compressed Natural Gas(CNG), methane(CH4), etc in the air. The module uses our MQ-4 sensor. It simplifies the interface to the odd pin spacing of the sensor and provides the interface through standard 4 x 0.1″ header pins.

It provides an analog output corresponding to the concentration of the gases in the air and an easy-to-use digital output. The onboard potentiometer can be used to set the maximum gas concentration beyond which the digital output gets triggered. The MQ-4 can detect natural gas concentrations anywhere from 200 to 10000ppm.

Just power the module with 5V set the threshold and you can start getting the gas concentration of the air around the sensor! An onboard LED signals the presence of any gas.

The digital output can be easily interfaced with microcontrollers and other circuits. The analog output can be hooked up to an ADC of a microcontroller to get a wide range of sensor readings. This is a simple-to-use compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air.
