The Touch Less Door Bell
Abstract
Proposed paper explain the implementation of “Touch less doorbell”based on object detection using an IR sensor.An IR sensor consists of an IR LED and photodiode.Together they are called as photo-coupler or opto-coupler.Touchless doorconsists of IR LED,, photodiode,resistors, potentiometer,general led Photodiode is a semiconductor diode which generates a potential difference or changes in its electrical resistance when it is exposed to light.Whenever any object comes close to IR sensor, the buzzer starts beeping and the LED glows .This system is suitable for securing doors, alarm in industrial plants and specially in safeguarding from COVID-19 virus
