Smart dustbin using arduino - How to make a smart dustbin using Arduino Uno and an ultrasonic sensor.
Components Used :
Arduino Uno
Ultrasonic Sensor HC SR04
Servomotor
Applications Of Ultrasonic sensor
Used in obstacle avoiding robots
RADAR sensing
Water Level monitoring
Security Alarm Projects
Working
The Ultrasonic sensor used here is HC SR04, which detects distance level in centimeters.circuityep.com.This is used to detect the distance at which an object is placed.
It is used as SONAR sensor or RADAR sensing an object.
The ultrasonic sensor has two parts one is an transmtter of sound another a receiver of sound.
Triger is a part which emits sound and echo which is used to listen the reflected sound wave.Time taken to receive signal determines the distance of an object.
Working of Smart DustBin
The ultrasonic sensor is the heart of smart dustbin project.Arduino is used to process the signals from ultrasonic sensor.The out put is a servomotor which is used to open and close the dustbin.
Initially arduino is programmed sothat the the servo motor is set to close condition of dustbin.
Whenever a motion is detected in front of ultrasonic sensor.The servomotor is activated and servomotor changes its position at a certain angle.
This condition is maintained
