Introduction: Motion Sensor Circuit With LED

About: I like to get back to the technical roots and try to make things without getting too complicated. Thanks for feedback…

Here is a tiny motion sensor circuit, that enables to switch something when someone moves in front of the sensor.

Step 1: Get Material

Materials needed:


Motion Sensor HC-SR501

Resistor (maybe)


Jumper Wire

Step 2: Plug Everything Together

Now plug the stuff together like shown and test it.

Step 3: Finish

It works! There can be made a lot of useful things with this circuit like automatic lights or a motion switch for endless appliances.
