PIR module usually requires an initial warm-up period for the sensing elements to come up to the operating mode. This usually takes not less than 30 seconds. So a 30 seconds delay is intentionally ...

Arduino Motion Sensor – Circuit and Working The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...

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.

In an era where homeowners frequently leave for work or education, robust security for residences is imperative. Traditional security measures, including window and door locks, present challenges such ...
