Products Introduction

The micro:bit Smart Health Kit is a carefully designed IoT learning kit that brings personal health and wellness into the classroom. Featuring a rich selection of sensors — including DHT11, PIR, UV sensor, soil moisture sensor, alcohol sensor, and more — students can build 12 authentic health-focused projects that address real-world concerns.

From automating hand hygiene and detecting harmful UV radiation to monitoring indoor air quality, sitting posture, and noise levels, every case places students in the role of a health engineer solving genuine human-centred challenges using programming and smart technology.

Built around the IoT:bit breakout board with ESP8266 Wi-Fi, DS1307 RTC, 16-channel GVS ports, and an on-board buzzer, the kit delivers professional-grade hardware in a beginner-friendly format. An OLED screen, servo, and LEDs complete the toolkit for rich, interactive feedback.

Compatible with MakeCode, Python, and JavaScript, and fully certified CE/RoHS for safe classroom use.

12 Real-World Smart Health Cases

Each case places students in the role of a health engineer solving a genuine wellness challenge — from hand hygiene automation and UV protection to posture monitoring and classroom noise control.

Touch-free Hands Washing Device
🪾
Case 01
Touch-free Hands Washing Device
Introduction
Maintaining clean and hygienic hands can prevent diseases from entering the mouth, thereby reducing the risk of intestinal and respiratory infectious diseases. Automating water valve control prevents recontamination during hand washing.
Function
Use a PIR sensor to detect human presence. When motion is identified, activate a servo to open the water valve automatically. When no movement is detected, the valve closes.
UV Light Detection Device
Case 02
UV Light Detection Device
Introduction
Excessive ultraviolet exposure causes melanin deposition in the skin, leading to darkening and permanent marks. UV rays accelerate skin aging — approximately 90% of human skin aging results from ultraviolet exposure.
Function
Detect UV light intensity using a UV sensor. When intensity readings are elevated, programme the servo to raise a parasol as a protective measure.
Temperature-controlled Fans
🌀
Case 03
Temperature-controlled Fans
Introduction
In rooms with high temperature and dry air, noses and throats are prone to dryness, congestion, and pain. The body's heat regulation system can become compromised in extreme heat, increasing the risk of heat stroke.
Function
Detect the temperature with the DHT11 sensor and display the value on the OLED screen. If the temperature exceeds the threshold, programme the fan to turn on automatically.
Alcohol Detection Device
🍸
Case 04
Alcohol Detection Device
Introduction
Excessive alcohol consumption in a short timeframe can damage the stomach lining and cause bleeding. An alcohol detection device can provide timely reminders to help regulate consumption.
Function
Detect alcohol concentration levels using the alcohol sensor and display readings on the OLED screen. When concentration exceeds the threshold, activate a red LED as a warning indicator.
Indoor Flower Watering Device
🍒
Case 05
Indoor Flower Watering Device
Introduction
Most plants make us healthier — one pot of green dill is equivalent to an air purifier for an 8–10 m² room, effectively absorbing harmful gases such as formaldehyde and benzene. A smart watering device ensures plants stay healthy with minimal effort.
Function
Judge if the plant needs watering by detecting the soil moisture value. If the value is too low, drive the servo to open the water valve automatically.
The Water Drinking Reminder
💧
Case 06
The Water Drinking Reminder
Introduction
Water regulates bodily circulation, maintains organ function, and keeps metabolic processes running smoothly. Insufficient water intake reduces digestive secretion and appetite, while also impairing the body's ability to regulate temperature.
Function
Activate a buzzer at set intervals to remind users to drink water. Users can open a water valve by pressing micro:bit buttons, with the valve closing automatically after several seconds.
Humidity & Temp. Monitor
🌡
Case 07
Humidity & Temp. Monitor
Introduction
Comfortable indoor temperatures range from 15–18°C with optimal humidity at 45–65%. When humidity drops below 35% and temperature exceeds 25°C, people feel uncomfortable. Above 35°C, sweat glands activate, potentially causing dizziness and fatigue.
Function
Detect humidity and temperature from the DHT11 sensor and display real-time readings on the OLED screen.
Step Counter
🚶
Case 08
Step Counter
Introduction
A step counter measures calories burned by counting steps, distance, speed, and time data. It helps users control the amount of exercise and prevent both insufficient and excessive physical activity.
Function
Count steps using the accelerometer built into the micro:bit, and display the cumulative step count data on the micro:bit LED matrix.
Sedentariness Reminder
🧊
Case 09
Sedentariness Reminder
Introduction
When sitting still for a long time, body weight concentrates on the lumbosacral area, causing muscle strain and lower back pain. Prolonged sitting also slows gastrointestinal motility, reducing digestive secretion and leading to bloating and constipation.
Function
Detect if someone is sitting in the chair; if yes, start a countdown timer and light up the LED if the sitting time exceeds the threshold, prompting the user to stand and move.
The Sitting Posture Reminder
🧍
Case 10
The Sitting Posture Reminder
Introduction
Poor sitting posture over extended periods negatively impacts physical appearance and can cause serious health issues including spinal misalignment, pelvic tilting, cervical spondylosis, and lumbar problems.
Function
Use the micro:bit's built-in accelerometer to detect the device's orientation and any changes in angle, enabling real-time monitoring and correction of the user's sitting posture.
Smart Trash Can
Case 11
Smart Trash Can
Introduction
If a trash can has no lid, it emits odours and affects the surrounding environment. If the lid requires manual opening, it can cause secondary contamination. A smart trash can solves both problems with automatic detection.
Function
Use a PIR sensor to detect human proximity and programme the servo to open the lid automatically when people approach, then close it again once they move away.
The Noise Detection in Classrooms
🔊
Case 12
The Noise Detection in Classrooms
Introduction
Noise severely harms health by affecting the nervous system, potentially causing insomnia, headaches, and cardiovascular issues. Prolonged noise exposure causes irreversible damage to the auditory system, such as neurological tinnitus or deafness.
Function
Use the micro:bit's built-in microphone to detect sound levels and display readings on the OLED screen. Activate LEDs in different colours based on detected noise intensity for real-time classroom monitoring.
