Reliable MQ2 Smoke Sensor Module With Alarm And Relay Output
✔️ DC5 to 30V Power Includes Reverse Protection And Threshold Adjustment

You get quick alerts on rising smoke levels without guessing about air quality. The module pairs a responsive sensor with a clear visual warning and a sounding buzzer you can hear across the room. Install it above a stove, inside a vehicle cabin, or near stored chemicals to catch hazards early. The integrated relay allows this smoke safety setup to trigger external alarms or cut power to equipment automatically.

✅ MQ2 sensor tracks smoke concentrations with a bright LED indicator and loud buzzer for immediate awareness.
✅ Supports DC5 to 30V input and guards against damage from accidental reverse wiring mistakes.
✅ Internal relay switches devices up to AC 220V 10A to complete a full smoke alarm network.
✅ Potentiometer adjusts the trigger level so you calibrate sensitivity for clean or dirty air zones.
✅ Durable PVC casing fixes quickly to surfaces and offers reliable service through more than 100,000 operations.

💡 What are the benefits of using a modular MQ2 smoke detection system with relay output?
You choose this architecture because it integrates into broader safety networks and keeps your wiring tidy.
- Quick recovery logic restores normal status automatically after smoke dissipates without resetting a button.
- Galvanized relay contacts let you daisy-chain units to a main control hub covering larger floor areas.
- Polarity protection diode prevents board failure if you swap leads during rough wiring adjustments.
- Extended operational lifespan reduces replacement downtime in busy workshops or vehicle fleets.
