In this CD4017 project, I have shown how to make a simple motion sensor switch using 4017 IC and E18-D80NK IR proximity sensor to automate the washroom light. You can also use this circuit as a motion ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

The motion sensor switch circuit can automatically turn on a water sprinkler but you can easily use it as a motion sensor light switch or motion activated alarm too. Before beginning the construction ...

Living objects with a body temperature above 0°C emit heat as infrared radiation, also known as thermal radiation, which is invisible to the human eye. PIR sensors, designed for this purpose, can ...

This smoke alarm built using a UM3562 sound generator can help maintain a smoke-free environment in apartments, offices, factories, restaurants, hospitals, etc. In this article, we’ll explore the ...

When vibrations are detected, the system triggers both a local audible alarm and sends email alerts to specified recipients. 📦 Hardware Components Component Quantity NodeMCU ESP8266 1 SW-420 ...

This motion detector alarm can detect a moving person from a distance of 1 meter. It uses a dual IR Transmitter-Receiver module HOA1405. When the sensor detects the reflected IR rays, alarm will sound ...

The main aim of this mini-project is to demonstrate the working of a PIR motion-based light bulbs. This is to mainly minimize energy consumption and save electricity bills. Sometimes people forget to ...

[Brad] was asked by his Sister to design a motion-based alarm that would help her catch her son sneaking out of the house at night. Obviously this didn’t need to be a long-term installation so he ...
