If you were on the fence about ESP32, these projects will get you started in no time ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

This research aimed to design, fabricate, and test a prototype of a 1-feed-line automatic chicken feeder, determining the designed functionality and feeding time, and comparing the performance of an ...

Abstract: In recent years, with the rapid advancement of unmanned systems, particularly unmanned aerial vehicles and autonomous vehicles, the accurate collection of external information has become ...

Abstract: This research investigates the application of an Arduino-based system for PET bottle plastic detection using the Esp32 Cam camera module and the Photoelectric Sensor E3Z B61. The study stems ...

Turbidity is considered a good measure of the quality of water as it is a measurement of how clear or cloudy the water is (the cloudier the water, the higher its turbidity). In theory, waterborne ...

With the fast development of energy harvesting technology, micro-nano or scale-up energy harvesters have been proposed to allow sensors or internet of things (IoT) applications with self-powered or ...
