Fig. 1: Author’s prototype Fig. 2: Block diagram of motion sensor alarm Circuit and working. The circuit diagram of the motion sensor alarm is shown in Fig. 3. It consists of a PIR motion sensor (MS1) ...

IR Sensor Pinout. The IR sensor has a 3-pin connector that interfaces it to the outside world. The connections are as follows: VCC is the power supply pin for the IR sensor which we connect to the 5V ...

This repository demonstrates how to implement motion detection using a PIR sensor with an LED and serial output across multiple platforms like Arduino Uno, ESP32, Raspberry Pi Pico, and STM32 Nucleo.

Using motion detectors and an Ardunio you can add a little extra wow to your Halloween displays this year. This article covers the circuits and the code to make that happen.
