Social distancing is the one of the best method to escape from COVID-19.I strongly recommend to stay at home. But we can't avoid some emergency visitsto some homes. When we arrived at in front of a house, first we search thedoorbell button/ calling bell button. And press the button. But in this specialsituation this doorbell button can cause the virus to spread. When someinfected person press the button the virus hold on that button and when a non-infectedperson touch this button the virus spread to that person. We can avoid thisdanger by using the touchless doorbell. The existing doorbell can convert to atouchless doorbell.How it works?
When show our hand in front of IR Sensor, The sensor will send signal toArduino board. And Arduino drive the relay. Relay is connected with doorbell.And finally the bell will ring.
