MQ-5 Gas Sensor Module - Detect H2, LPG, CH4 & CO with Precision
Build reliable gas detection and safety monitoring systems with the MQ-5 Gas Sensor Module from The Engineer Store, Bengaluru. This versatile semiconductor sensor accurately detects Hydrogen (H2), Liquefied Petroleum Gas (LPG), Methane (CH4), and Carbon Monoxide (CO), making it an essential component for home safety alarms, industrial leak detection, and IoT-based air quality projects. Features both analog and digital outputs for seamless integration with Arduino, ESP32, Raspberry Pi, and other microcontrollers. Fast shipping, 7-day warranty on manufacturing defects, and dedicated technical support included.

Why Choose the MQ-5 Gas Sensor Module?
- Multi-Gas Detection: Reliably senses H2, LPG, CH4, CO, and natural gas in a single compact module - ideal for comprehensive safety systems
- Dual Output Flexibility: Analog output for precise concentration measurement and digital output with adjustable threshold for simple alarm triggering
- Low Cross-Sensitivity to Alcohol: Compared to MQ-2 and MQ-3 sensors, the MQ-5 offers reduced sensitivity to alcohol vapors, providing cleaner readings for combustible gas detection
- Onboard Signal Conditioning: LM393 comparator and potentiometer eliminate the need for external circuitry - connect directly to your microcontroller
- Plug-and-Play with Arduino: Simple 4-pin header (VCC, GND, AO, DO) works out of the box with analogRead() or digitalRead() functions
- Visual Feedback: Power and trigger LEDs provide instant status indication without needing a serial monitor
- 100% Authentic: Sourced directly from trusted, authorized suppliers - quality verified before dispatch
- Fast Delivery: 1-5 day shipping, 7-8 day delivery from our Bengaluru warehouse; same-day delivery available within Bengaluru
- Expert Technical Support: Full guidance on wiring, calibration, and code via email and WhatsApp - 24/7
Project Ideas
- LPG Kitchen Leak Detector: Build a smart kitchen safety alarm that triggers a buzzer and sends mobile notifications when LPG gas leaks are detected - protect your home with an affordable IoT solution
- Methane Monitoring for Biogas Plants: Monitor CH4 concentration in biogas digesters and fermentation setups to optimize gas production and ensure safe operating levels
- Hydrogen Leak Alert System: Create a safety system for hydrogen fuel cell labs, battery charging stations, or electrolysis setups that detects H2 leaks and activates exhaust fans automatically
- Carbon Monoxide Safety Monitor: Design a CO detector for enclosed spaces like garages, workshops, or generator rooms - sound an alarm when CO levels exceed safe thresholds
- Smart Home Gas Safety with IoT: Combine with ESP32 or ESP8266 and Blynk/MQTT to build a Wi-Fi-connected gas monitoring dashboard with real-time alerts on your smartphone
- Multi-Sensor Air Quality Station: Pair the MQ-5 with MQ-135 (air quality), DHT22 (temperature/humidity), and a dust sensor to create a comprehensive environmental monitoring station
