MQ2 Smoke Gas LPG Butane hydrogen Sensor Module - IoT

This item is Factory Sealed under category - IoT The MQ-2 Smoke and Gas Sensor Module is a reliable and cost-effective solution for detecting a range of gases, including LPG, butane, methane, hydrogen, alcohol, and smoke. Designed for safety and environmental monitoring applications, this module features a high-sensitivity gas sensor and an onboard potentiometer for sensitivity adjustment. The module operates on a 5V power supply and outputs both analog and digital signals, making it compatible with various microcontroller platforms such as Arduino and Raspberry Pi. The analog output provides real-time gas concentration readings, while the digital output is triggered when gas levels exceed a predefined threshold. Its compact design and ease of integration make the MQ-2 sensor ideal for applications like gas leakage detection, air quality monitoring, and fire safety systems.
