Topic: Covid19 sanitizer tunnel (Read 1 time) previous topic - next topic


Good day

I'm trying to program a arduino nano with 2 PIR sensors and a water float sensor and I'm not very good at programming they will be used to turn on a relay  that is for the pump, so when the person gets neer the tunnel it should start the pump and the person should walk through it to the place we're he/she should be and then through it when they go home, so the person should be able to walk both sides in and out, so I thought the the relay must turn on when the person gets Close to the tunnel and stay on for 20 second and then turns off, then detect if the person leaves the other site it should not turn on again and it should need to have a few led's to indicate if the sanitizer tank is empty and when it is right for the next person. Please help me its for my local school
