About this project

What you'll build: A safety alarm that sounds a buzzer and lights an LED when a gas sensor detects smoke or LPG above a set level.

Why it's a good starter: It is a genuinely useful safety build with a clear threshold-based logic.

What you'll learn: Reading an analog gas sensor, setting a sensible threshold, and driving a buzzer/LED alert.

Milestones

10 marks 5d
List parts, draw the circuit, and describe the alarm logic; submit your plan and sketch.
2. Wire & read the gas sensor
30 marks 10d
Connect the MQ-2 and print live gas readings in clean and smoky air. Submit your readings.
3. Add the alarm
30 marks 10d
Trigger the buzzer and LED above a calibrated threshold and reset when clear. Submit a demo video.
4. Testing & Polish
15 marks 6d
Test with a safe smoke source and tune the threshold to avoid false alarms.
5. Demo & Short Report
