How to Connect a Transistor as a Switch in a Circuit
The PIR motion sensor does this. Once it detects motion, it outputs current to its outpin pin, which is pin 3. Since this output is current, it can be used to turn on the transistor. Since the PIR motion sensor outputs current and the transistor is a switch that turns on by electrical current, it''s a perfect switch that works complementary with the transistor. A mechanical switch is when a ...
