Product Overview

Build a Real Smart Home, Line by Line

The micro:bit Smart Home Kit transforms students into home automation engineers. By building hands-on scenarios — a smart windowsill, an automated wardrobe, a self-monitoring fish tank — students gain real experience in sensor programming, motor control, and intelligent system design.

11 Progressive Smart Home Scenarios

From voice-activated lights to intrusion detection, each project builds on the last — developing complexity and confidence in a natural progression.

⛏

Sensors + Motors + Display

Students experience the full IoT loop: sense → process → actuate. Combine noise, light, temperature, and crash sensors with servos, DC motors, a pump, and an OLED display.

💻

Programmable with MakeCode & Python

Works with Microsoft MakeCode's block-based editor for beginners, then scales to Python and JavaScript for more advanced learners — no platform switching required.

Why It Works

Designed for Real-World Engineering

Every component connects a classroom concept to a real system students interact with every day at home — making learning immediate, relevant, and unforgettable.

🏠

Real Home Scenarios

Students build replicas of real-world home systems — smart doors, automated fans, plant watering — not abstract exercises. Every project mirrors actual IoT engineering.

🔌

Diverse Sensor Suite

Eight different input and output modules — sound, light, temperature, crash, soil moisture, relay, servo, and DC motor — expose students to the full range of IoT sensing and actuation.

💻

micro:bit + MakeCode / Python

Progressive coding from visual blocks to text-based Python — the same hardware grows with the student's skill level from beginner to advanced.

📈

OLED Data Display

The integrated OLED screen lets students display live sensor readings — temperature, noise levels, timestamps — building data visualization and feedback loop understanding.

🤖

Motor & Servo Control

DC motor for fans and rotating mechanisms, 180° servo for doors and windows, and a submersible pump for plant watering — introducing electromechanical control concepts.

🏭

Cross-Curriculum STEAM

Projects naturally span physics (circuits, motors), computer science (programming logic), environmental science (sensors), and engineering design — all in one kit.

What's Inside the Box

Key Hardware Components

A complete ecosystem of sensors, actuators, a controller, and a display — everything needed to build a functioning smart home automation system from day one.

Controller

micro:bit + 3V sensor:bit

The micro:bit is the programmable brain — small, powerful, and accessible. The 3V sensor:bit expansion board provides clean, labeled ports for every sensor and actuator in the kit, making wiring intuitive and error-free.

Soil Moisture SensorWater level / hydration

Actuators

Motor, Servo & Pump

Three types of actuators give students full control of physical systems — from spinning a fan blade to opening a door to watering a plant. Combined with a relay for switching, this covers the core of real home automation hardware.

Classroom Projects

11 Smart Home Challenges

Each project is a self-contained smart home engineering challenge that builds sensor programming, actuation logic, and system design progressively.

Voice-Activated Lights

Use the noise sensor and Rainbow LED to build lights that switch on when they detect a sound — just like a real smart home clap-switch or voice command system.

Smart Fan

Program the TMP36 temperature sensor to automatically spin the DC motor fan when temperature rises above a threshold, displaying live readings on the OLED screen.

Automated Window

Connect the light sensor and 180° servo to open and close a window model automatically based on ambient brightness — mimicking real smart blinds.

Smart Wardrobe

Build a wardrobe that uses the crash sensor to detect opening and the Rainbow LED to illuminate the interior automatically — just like modern smart furniture.

Fish Tank Monitor

Use the soil moisture sensor as a water level detector to trigger the submersible pump, simulating an automated top-up system for an aquarium or plant watering station.

Intrusion Detection

Combine the crash and noise sensors with the buzzer to build a simple home security alarm — triggering an alert when unexpected contact or sound is detected.

Smart Door

Use the servo motor and crash sensor to build an automatic door that opens when someone approaches and closes after a timed delay — simulating real smart entry systems.

Noise Level Meter

Program the noise sensor and OLED display to measure and visualize ambient sound levels in real time — building a functional decibel monitor for any room.

Health & Comfort Monitor

Combine the temperature sensor, light sensor, and OLED display to track room comfort — alerting when conditions fall outside healthy ranges for temperature or lighting.

Automated Plant Watering

Use the soil moisture sensor to detect dry soil and trigger the submersible pump to water plants automatically — a fully functional smart irrigation system.

Smart Home Dashboard

Connect all sensors simultaneously and program the OLED to display a live dashboard showing temperature, noise, light levels, and system status — the ultimate integration project.
