Smart Motion Detection System using IoT: A NodeMCU and Blynk Framework

Kazi Kutubuddin Sayyad Liyakat

Abstract

A motion detector is a device that senses movement and triggers an action, such as turning on a light or sounding an alarm. Usually, motion detectors have been wired into home security systems, but with the advancements in IoT technology, they can now be connected to the internet for remote monitoring and control. This makes it possible to secure our homes and workplaces in a more practical and adaptable manner. To create our IoT motion detector, we will need a few additional components such as a passive infrared (PIR) sensor, a buzzer, and an LED. The PIR sensor is a small, low-power device that detects infrared radiation emitted from moving objects. It is commonly used in motion detectors as it is highly sensitive and requires minimal power. The IoT Motion Detector is a device that uses sensors to detect motion in its surroundings. It is equipped with a NodeMCU board, which is a low-cost open-source microcontroller designed for IoT projects. Because this board has WiFi integrated right in, connecting to the internet and interacting with other devices is a breeze. The Blynk app, on the other hand, is a user-friendly platform that allows users to control and monitor their IoT devices remotely.
