PIR modules have a 3-pin connection at the side or bottom. The pinout may vary between modules so triple-check the pinout! It's often silkscreened on right next to the connection (at least, ours is!) One pin will be ground, another will be signal and the final one will be power. Power is usually 3-5VDC input. When object comes in detecting area it will return 1 from output pin otherwise it return 0. The IR sensor itself is housed in a hermetically sealed metal can to improve...
IntroductionLong-range wireless communication without internet, Wi-Fi, or cellular network is no longer a dream. Using the LoRa-02 SX1278 module with ESP32, you can transmit data up to 8–10 km using radio frequency (433 MHz) with extremely low power consumption.The ability to transmit data over 8–10 km opens doors for remote monitoring, smart agriculture, and many other applications where conventional connectivity options fall short.Imagine a world where devices can communicate over vast distances without relying on traditional networks. The LoRa-02 SX1278...
