Overview
We investigated the motion sensors on the market.
We will check the specifications of each sensor from the mechanism of the motion sensor, program it, and use it by electronic work.
When using the ESP32 for electronic work, we test in enviable environments such as cold objects, small objects, outdoors, and indoors, and evaluate which sensor is the easiest to use and has the best performance.
