Industrial Gas Leak Detector Kit
Industrial Gas Leak Detector Kit with Arduino — Build a Smoke-Activated Spray System
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
In industrial environments, a rapid smoke response can prevent equipment damage and protect lives. This kit lets you prototype that exact logic: an Arduino reads the MQ‑2 gas sensor and, when smoke crosses a set threshold, triggers a relay to power an air freshener spray pump — simulating an automatic ventilation or fire‑suppression action. All parts arrive ready to plug together on a breadboard, no soldering required.
What You'll Build
A complete safety demonstrator that continuously monitors ambient air. Once smoke or combustible gas levels exceed the safe limit, two red LEDs flash and the relay activates, turning on a small spray pump (pump not included). The response is immediate and repeatable, making it ideal for science exhibitions, ATL tinkering sessions, or CBSE practicals where real‑world relevance matters.
What You'll Learn
- Interface an MQ‑2 sensor with Arduino and read analog gas concentration values
- Calibrate a smoke detection threshold using the sensor’s potentiometer and code
- Control a high‑power device (spray pump) safely via a relay module and 1N4007 flyback diode
- Combine sensors, actuators, and indicators on a breadboard to form a cohesive safety system

Who This Kit Is For
Young innovators at ATL Tinkering Labs, CBSE students (Class 6–10) exploring sensor‑based projects, and hobbyists curious about industrial safety automation. With adult supervision, even a 10‑year‑old can wire the circuit and load the pre‑written code. Perfect for school science fairs where a live gas‑leak response demo earns top marks.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Open the AI companion from the QR code – it shows wiring diagrams, troubleshoots common mistakes, and highlights the exact component placement. If you still need help, our team responds over WhatsApp within a few hours.
Does the kit include the spray pump?
No, the kit focuses on the detection and control electronics. You can connect any 5V DC air freshener spray pump or a small 5V fan. Most school labs already have a compatible pump, or you can pick one up locally.
How do I set the smoke level that triggers the relay?
You adjust the MQ‑2’s onboard potentiometer and fine‑tune the threshold value in the Arduino code. The AI companion walks you through calibrating the sensor near a tiny smoke source (like a matchstick) so the system reacts exactly when you want it to.
Can the project be submitted for a CBSE or ATL science exhibition?
Absolutely. It demonstrates a practical industrial safety system, aligns with sensor and automation curriculum, and includes complete documentation. Many students have used this kit in national‑level exhibitions and reported high evaluation scores.
