IMAGINATION TO REALITY

Project Description:

The Automated Waste Separation System is designed to separate the dry waste and wet waste. We are using sensors to reduce pollution and enhance waste management efficiency. This project integrates components such as Arduino, servo motors, and soil moisture sensors to automate waste sorting, ensuring each type of waste is treated separately.

Components Required:

1. Arduino UNO with cable x 1
2. Soil Moisture Sensor x 1
3. Servo Motors SG90s x 1
4. Ultrasonic sensor HC-SR04 x 1
5. Jumper wires: male to female x 7
   : male to male x 3

Benefits:

• Efficiency: Automated sorting reduces manual labor and increases sorting accuracy.
• Environmental Impact: Proper waste segregation minimizes pollution and enhances recycling and composting efforts.

Connections:

Connection of Arduino with ultrasonic sensor:

• Arduino pin no. 12 to trig.
• Arduino pin no. 11 to echo
• Arduino pin 5v to VCC
• Arduino pin GND to GND

Connection of Arduino to Soil moisture sensor:

• Arduino pin 5v to VCC
• Arduino pin GND to GND
• Arduino pin A0 to A0

Connection of Arduino to Servo motor SG90s:

• Arduino pin 5v to VCC
• Arduino pin GND to GND
• Arduino pin 8 to the signal of the servo motor.
