Sensor HC SR501 PIR

Arduino detect a hand gesture by using PIR sensor (hc-sr501).

Jan 06, 2021· Hello again, In this blog, We will learn about how PIR sensor (HC-sr501) work and we can control 230v bulb with hand gesture by using PIR sensor, relay, and Arduino. Using Arduino to get a signal from the PIR sensor and then send a signal to relay to switch a load and turn on the 230v blub. In the Arduino project, We start with basic whenever ...
