MQ-2 LPG, Butane, Propane, Methane, Alcohol, Smoke & Hydrogen Gas Sensor Module

The MQ-2 Gas Sensor module is designed for detecting gas leaks in both homes and industrial settings. It can sense a variety of gases, including LPG, i-butane, propane, methane, alcohol, hydrogen, and smoke. The module features a built-in variable resistor, allowing you to adjust the sensor’s sensitivity as needed.

Features:

• Dimensions: 32mm × 22mm × 27mm
• Sensor chip: LM393, ZYMQ-2
• Operating voltage: DC 5V
• Dual signal output: analog and TTL
• Analog output ranges from 0–5V, with higher gas concentrations producing higher voltages
