Build a Forest Fire Detector with BBC Micro:bit - Early Warning STEM Kit

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

Forest fires cause massive damage, but early detection can save lives and habitats. With this kit, your child builds a working detector that triggers an alarm when temperature or smoke levels rise-just like the systems used by forest rangers. No prior experience is required, and all connections are made with simple crocodile clips.

What You'll Build

A BBC Micro:bit-powered environmental monitor that uses a thermistor to sense sudden heat and an MQ-2 gas sensor to pick up smoke particles. When both sensors report values above safe thresholds, two red LEDs flash aggressively and a piezo buzzer sounds a continuous alert. It's a hands-on replica of a real forest fire early-warning station-portable, battery-operated, and fully programmable.

What You'll Learn

• Connect and read analog data from a thermistor and MQ-2 gas sensor using alligator clips
• Program conditional logic on the Micro:bit to trigger visual and audible alarms
• Understand how temperature and smoke concentration combine to indicate a fire
• Calibrate sensor thresholds so the alarm activates only under realistic fire conditions

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Children aged 8-10 who are curious about how electronics and sensors can protect the environment. It's perfect for CBSE Class 4-5 science projects, activity clubs, and home-based STEM exploration. The alligator-clip assembly means no soldering, keeping the experience safe and frustration-free for young inventors in India.

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.
