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 ...

Based on a PIR motion sensor and buzzer trigger mechanism. Designed in [EasyEDA/KiCad/etc.], optimized for a small PCB footprint. Tested on breadboard before designing final PCB. Built as part of my ...

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 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 ...

[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 ...

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 ...
