MQ-5 LPG & Natural Gas Sensor Module
Ensure the safety of your home or workplace with the MQ-5 Gas Sensor Module. This sensor is specifically designed for the detection of Liquefied Petroleum Gas (LPG) and Natural Gas (Methane), making it the ideal component for building highly reliable gas leak detectors and safety alarm systems.
The MQ-5 is highly sensitive to these common combustible gases and provides a fast response time. This breakout module simplifies its use by incorporating all the necessary electronics, including a comparator for a stable digital signal. It offers a flexible dual-output system: an **Analog Output (A0)** that provides a voltage proportional to the gas concentration, and a **Digital Output (D0)** that triggers when the concentration exceeds a preset level.
You can easily calibrate the sensor’s trigger point using the onboard potentiometer, tailoring it to the specific safety requirements of your project. The MQ-5 is an essential sensor for anyone looking to build a robust gas monitoring or alert system with an Arduino or other microcontroller.
Key Features:
- Sensor Model: MQ-5
- Primary Detection: High sensitivity to LPG, Natural Gas, and Coal Gas
- Dual Output: Provides both Analog (voltage) and Digital (HIGH/LOW) signals
- Adjustable Sensitivity: Onboard potentiometer to set the digital alarm threshold
- Operating Voltage: 5V DC
- Interface: 4-pin header (VCC, GND, D0, A0) for easy interfacing
- Long Life and Stability: Designed for reliable, long-term operation
Applications:
The MQ-5 sensor is perfectly suited for a range of safety-critical applications, including domestic gas leak alarms, industrial combustible gas detectors, portable gas monitors, and environmental safety systems for kitchens, factories, and labs.
