One micro:bit, 8 Security Experiments - Home Security Motion Sensor Kit v7 for Classroom Learning

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

Instead of just blinking LEDs, students create a working home security system using a single micro:bit. This kit turns the classroom into a security lab, with 8 structured experiments that teach inputs, outputs, sensors, and wireless radio-all from one board. Perfect for a class station or individual exploration, each experiment card guides the builder step by step.

What You'll Build

By the end of the 8 experiments, the builder will have a motion-triggered alarm, temperature monitoring, push-button arming, visual alerts, and a radio link that sends alerts between two micro:bits. Each experiment builds on the last, culminating in a multi-sensor security station that demonstrates real-world system design. No soldering or complex tools are needed; everything connects with crocodile clips and breadboard wires.

What You'll Learn

• Program motion detection using a PIR sensor and trigger visual/audio alarms on the micro:bit
• Read and display temperature and humidity data from the DHT11 sensor in real time
• Build input interfaces with push buttons to arm and disarm a security system, controlling LEDs
• Transmit security alerts wirelessly between micro:bits using the built-in radio module

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for Indian classrooms, this kit fits perfectly into ATL Tinkering Labs, CBSE Class 6-10 ICT and coding sessions, and school STEM clubs. It's also a practical hands-on resource for B.Tech ECE 1st-year introductory projects or summer workshops at IIT/NIT/VIT campuses. With one board and eight experiments, a single kit can serve a small group or rotate through a class station.

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.
