As part of a collaborative project, my team and I designed and built a motion detector alarm circuit. This project involved integrating sensors to detect movement and trigger an alarm, enhancing ...

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 ...

The PIR motion sensor light wiring diagram is shown below. The basic idea is to amplify the output signal from the PIR sensor to control the relay, which, in turn, switches the bulb on or off. The ...

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 ...

This contacts (or spare contacts) can also be used to activate a high-power warning alarm. Please note that, here T1 is wired as a mini electronic timer. Even after the PIR relay switched off, output ...
