A fire detection and response system using the ESP32-S3 and MLX90640 IR thermal camera. Detects high-temperature zones via thermal imaging and triggers a relay-based actuator, sending real-time fire ...

In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

モジュールをマグネットでパチパチくっつけていくことで電子回路を組み立てられる「littleBits(リトルビッツ)」に、マイコンボード「Arduino」モジュールが登場。ブレッドボードやはんだ付けや面倒な配線などが一切不要で電子回路を組み立てて、Arduino ...

In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...
