If these sensors can control fans, lights, or other electronics by themselves, you can only make them stronger by hooking them up to a microprocessor development board such as an Arduino.

If you can install a conventional outdoor light fixture, you can install a motion sensor light, although aiming and adjusting it takes extra effort.

Historically, we’ve used IR and ultrasonic sensors but [Makers Mashup] decided to use an ESP32-Cam as a motion sensor in his latest animatronic creation.

Arduino’s Plug and Make Kit lets your hacking imagination run wild, sans solder Daisy-chain tiny boards into weather stations, game controllers, and way more.
