The Detective Dustbin is an intelligent waste management system designed to provide automated functionality and security features. It employs various components, including a Raspberry Pi Pico microcontroller, ultrasonic sensors, motion sensors, a buzzer, LED, and a Bluetooth module (HC-05).
- Raspberry Pi Pico - 1
- Ultrasonic Sensor - 2
- Motion Sensor - 1
- Buzzer - 1
- LED - 1
- Bluetooth Module HC-05 - 1
The dustbin is equipped with two ultrasonic sensors to detect the proximity of an object. When someone approaches the dustbin within a minimum distance of 15cm, the ultrasonic sensor triggers the dustbin to automatically open. The dustbin will close automatically after 5 seconds.
The motion sensor serves as a security feature. It detects motion in front of the dustbin, acting as a spy-like system. If anyone crosses the dustbin, the buzzer is activated, providing an alert.
The ultrasonic sensor is utilized not only for proximity detection but also to measure the percentage of the dustbin's capacity filled. This feature helps users monitor the waste level in real-time.
The Bluetooth module (HC-05) enables remote control and monitoring. Users can switch on/off the ultrasonic sensor for the automatic open-close function using a mobile application. Additionally, the motion sensor's data is transmitted via Bluetooth to a paired device, allowing users to receive alerts about detected motion.
- Proximity Detection: Stand within 15cm of the dustbin to trigger automatic open-close functionality.
- Motion Detection: The motion sensor detects and alerts if anyone crosses in front of the dustbin.
- Quantity Measurement: The ultrasonic sensor measures the percentage of the dustbin's capacity filled.
- Bluetooth Control: Use the Bluetooth-connected mobile application to toggle the ultrasonic sensor on/off for automatic open-close and receive motion detection alerts as notifications.
- App: Android Bluetooth Terminal App
- Usage: Control the dustbin remotely and receive Bluetooth notifications.
