Aju developed an automatic door sensor system using a Micro:bit, an ultrasonic sensor, and a servo motor, creating a hands-free solution for opening doors. The ultrasonic sensor detects nearby objects or people by emitting sound waves and measuring how long they take to return. When the sensor detects movement within a set range, the Micro:bit processes this data and activates the servo motor to open the door. The system automatically closes the door after a set time or when no motion is detected. This project showcases a practical application of automation that enhances convenience, hygiene, and efficiency in various environments.
