Gas Leak Detection System with MQ-2 Sensor
A safety-critical gas leak detection system using the MQ-2 smoke and gas sensor. Detects LPG, propane, methane, and smoke. Triggers an audible alarm via buzzer and a visual LED alert when gas concentration exceeds the set threshold.
Temperature & Humidity Monitor with DHT11 and LCD
A real-time temperature and humidity monitoring system using the DHT11 sensor and a 16x2 LCD. Displays live readings with min/max tracking. Ideal for room climate monitoring or greenhouse environments.
Arduino Radar System with Processing Visualization
Build a mini radar system using an Arduino, a servo motor, and an HC-SR04 ultrasonic sensor. The servo sweeps 180° while the sensor scans for objects. Data is sent to a Processing sketch that renders a real-time radar display on your computer.
Smart Blind Stick with Obstacle Detection
An assistive device for visually impaired individuals. Uses an ultrasonic sensor to detect obstacles ahead and alerts the user with a buzzer and vibration motor. Lightweight and battery powered.
Smart Dustbin with Auto-Open Lid
Build an automatic dustbin that opens its lid when it detects someone approaching. Uses an HC-SR04 ultrasonic sensor to detect proximity and a servo motor to control the lid. Perfect for touchless hygiene.
