Gas Detector Kitchen Alert Kit with Arduino Uno + Sensor
Arduino Uno Gas Detector Kitchen Alert Kit — Ensure Home Safety with Simple Electronics
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Indian kitchens are the heart of the home, but an LPG cylinder leak or forgotten smoke from cooking can escalate into a hazard within minutes. This Gas Detector Kitchen Alert Kit lets young makers construct a functional safety device that senses dangerous gases like LPG and smoke. When the MQ-2 sensor detects abnormal levels, it instantly triggers a loud active buzzer and illuminates three red LEDs, providing a clear warning to all occupants.
What You'll Build
The builder assembles a breadboard circuit around the Arduino Uno R3, integrating the MQ-2 gas sensor. The final model acts as a miniature kitchen safety monitor — place it near the stove or cylinder, and it reacts to smoke or gas leaks with audio-visual alerts. Children gain a tangible project they can actually use in daily life.
What You'll Learn
- Wiring MQ-2 gas sensor to Arduino for analog readings
- Programming threshold logic to trigger buzzer and LEDs
- Controlling multiple outputs from a single sensor input
- Troubleshooting sensor sensitivity for LPG and smoke

Who This Kit Is For
This kit is designed for curious young minds in India, from ATL Tinkering Lab students exploring smart home concepts to CBSE Class 11-12 students working on science exhibitions. It’s also suitable for B.Tech ECE/EEE freshers at institutions like VIT or BITS needing a quick safety system prototype. The simple assembly means even children as young as 5 can participate with adult guidance.
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?
Scan the QR code in the box to chat with our AI companion, which knows every wire and code line for this kit. Human help is also available on WhatsApp within 24 hours.
Can this detect LPG from a real cylinder?
Yes, the MQ-2 sensor is calibrated for LPG, so it will trigger when you simulate a leak near the kit. Always test in a well-ventilated area and never use actual gas for demonstration without adult supervision.
Is the kit safe for children aged 5-8?
The components run on a 9V battery, making it extremely low-risk. However, we recommend adult assistance for inserting pins and understanding the concepts for very young builders.
Can I use this as a permanent kitchen device?
This kit is an educational prototype. For continuous kitchen monitoring, you would need to add a power adapter and encase the electronics, but it demonstrates the core principle effectively.
MQ-2 fires buzzer and red LED when LPG or smoke detected. Basic kitchen safety.
