The MQ-2 Gas Sensor Detector Module is a versatile and widely-used component designed for detecting various gases, including smoke, liquefied petroleum gas (LPG), butane, and hydrogen.
Hanwei Electronics manufactures this sensor module, which is crucial for applications where monitoring gas.
concentrations is essential, such as in home safety systems, industrial environments, and gas leak detection devices.

The MQ-2 sensor module operates on the principle of a semiconductor gas sensor. It consists of a tin dioxide (SnO2) sensing layer that interacts with the target gases.
When these gases are present, the sensor’s conductivity changes, leading to alterations in electrical resistance.
This change converts into an analog voltage signal, so providing an accurate measure of the concentration of the detected gases.

A notable feature of the MQ-2 sensor module is its ability to detect a wide range of gases, but making it a versatile solution for gas sensing applications.
Its sensitivity to multiple gases, including smoke and flammable gases like LPG and butane, but ensures comprehensive monitoring for potential hazards.

Designed for easy integration into electronic systems, the MQ-2 sensor module typically includes analog output pins for convenient connectivity with microcontrollers like Arduino.
This user-friendly design enables the incorporation of the sensor into various projects.
ranging from home gas leak detectors to industrial safety systems.

Applications of the MQ-2 sensor module are diverse.
In homes, it plays a crucial role in ensuring the safety of residents by detecting smoke and gas leaks.
