Arduino Lab Gas Monitor Kit – Build an Automatic Leak Detection System with SMS Alert

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a student-run chemistry lab or a university research facility where flammable gases are common. A minor leak can escalate into a disaster. With this kit, you build a proactive safety system that sniffs out gas leaks in real time, automatically shuts off the gas supply via a solenoid valve, blasts an alarm, and sends an SMS to the lab supervisor’s phone. No more relying on manual checks—this is industrial-grade vigilance you can prototype and deploy yourself.

What You'll Build

You’ll assemble a dual-sensor monitor using MQ-2 for combustible gases and MQ-7 for carbon monoxide. The Arduino processes analog signals and triggers a relay to close a 12V solenoid valve, cutting gas. A buzzer sounds, LEDs flash, and SIM800L sends SMS with leak type. The system runs

Choose your assembly option:

• Soldering Kit — 25W soldering iron, 60/40 solder wire, flux, and small perfboard for permanent assembly.
• Breadboard Combo — 800-point full-size breadboard with 65-piece jumper wire pack for solderless prototyping.
