SMART WASTE SEGREGATION USING ARDUINO UNO

SMART WASTE SEGREGATION USING ARDUINO UNO

(Smart Dustbin)

• Waste management is a pressing global challenge that requires innovative solutions.

• The traditional waste management methods often lack efficiency and sustainability.

• Introduction to the concept of "Smart Waste Segregation" using Arduino, a versatile microcontroller platform.

• Even though there are large scale industrial waste segregators present, it is always much better to segregate the waste at the source itself.

• The occupational hazard for waste workers is reduced also the segregated waste could be directly sent to the recycling and processing plant instead of sending it to the segregation plant than to the recycling plant.

Working

Smart Waste Management System is a system which provides a solution to separate dry and wet wastes and also share information through internet to help in better monitoring of the system. The steps involved in building the system are as follows:- 

•  Step 1:- Identification of the wastes. This prototype model focuses only to separate dry and wet wastes. So to identify the types of waste, an IR sensor is used to sense an object near it and capacitive soil moisture sensor to measure the moisture content. When only IR sensor sense, it identifies as dry waste, and if both IR sensor and capacitive soil moisture sensor senses or detects. 

•  Step 2:- Programming of arduino. Programming of arduino is done using arduino IDE with embedded C. Coding is done in such a way that takes sensor value as input and accordingly gives instructions to rotate servo motor and also displaying output in LCD. 

•  Step 3:- Using appropriate sensors. IR sensor is used to detect the presence of waste, capacitive soil moisture sensor is used to detect the amount of moisture content in the given waste and Ultrasonic sensors are used to detect the amount of wastes in the garbage bin so as to prevent it from overfilling. 

•  Step 4:- Rig up of circuit. After choosing appropriate sensors, next step is to rig up the circuit according to the circuit diagram. 

•  Step 5:- Testing of the circuit. Testing of circuit is the last step by giving various types of wastes (dry and wet) and validating if the sensors are correctly identifying and dumping the waste in correct dustbin.

Circuit Diagram

1. Connect the VCC (5V) and GND pins of the ultrasonic sensors to the 5V and GND pins ofthe Arduino Uno respectively. 

2. Connect the TRIG and ECHO pins of the ultrasonic sensors to digital input/output pins of the Arduino Uno (for example, TRIG to pin 10 and ECHO to pin 11). 

3. Connect the VCC (5V) and GND pins of the servo motors to the 5V and GND pins of the Arduino Uno respectively. 

4. Connect the control signal pins (typically marked as SIG or S) of the servo motors to digital pins of the Arduino Uno (for example, servo 1 to pin 5 and servo 2 to pin 6). 

5. Connect the anodes of the LED indicators to digital pins of the Arduino Uno (for example, LED 1 to pin 2 and LED 2 to pin 3). Connect the cathodes of the LEDs to GND. 

6. Optionally, connect a power source (e.g., a battery pack) to the VIN and GND pins of the Arduino Uno if you're not using USB power.
