Smart Home and IoT Projects Built by Kids

These students present their innovative IR-based hand hygiene station, featuring an automatic hand washer and hand dryer. They demonstrate how sensors trigger the water flow and the fan, a great example of practical, automated solutions.

Two students demonstrate a parking sensor they built, using an Arduino, ultrasonic sensor, and LEDs. They explain how different colored lights indicate the proximity of an object, a project with clear real-world applications for vehicle safety.

This team presents a solar-powered motion sensor that uses a PIR sensor and Raspberry Pi to detect movement. They explain how it can be used for security or wildlife tracking, showcasing their knowledge of sustainable technology.

Here, students demonstrate their automatic plant watering system. They explain how a soil moisture sensor detects dryness and triggers a pump, a smart and sustainable solution for plant care powered by a solar panel.

A student showcases his sound-activated "safe door" project. He explains how a sound sensor sends a signal to an ESP8266 module, which then controls servo motors to open and close the doors, a clever application for hands-free access.

This team demonstrates a sequential LED lighting system controlled by an ultrasonic sensor, designed to function like a parking assist system. As a toy car gets closer, more LEDs light up and a buzzer sounds, showing a practical use of distance sensing.

This group of students presents their "Enviro Time" smartwatch prototype built with a Raspberry Pi. It uses an MQ2 sensor to measure air quality and a BMP280 sensor for altitude and temperature, a fantastic project combining wearable tech and environmental monitoring.

A fifth-grade student explains her solar-powered buzzer sensor project. She details how the system uses a Raspberry Pi and solar-charged batteries to detect motion and sound an alarm, making it effective for home security day and night.

A fourth-grader demonstrates his security car system. He explains how an ultrasonic sensor detects a nearby object and triggers a loud buzzer, a simple but effective alarm system built from basic robotic components.
