The circuit diagram of the motion detector using NE555 timer is shown in Fig. 1. It is built around 230V AC primary to 9V, 300mA secondary transformer X1, ...

This cool project has a geek building a life-size version of that turret and equipping it with motion detection and a laser eye. That laser eye appears to be a red laser pointer, and it looks ...

This motion detector circuit is versatile and can be installed in various locations, such as the front gate or staircase. Upon detecting movement, the PIR sensor triggers the relay, initiating the ...

This circuit produces an alarm whenever someone comes near the spotting range of its passive infrared (PIR) motion sensor.

If you live in an area with lots of wildlife and would like to get photos without having your camera constantly at the ready, you can repurpose a cheap camera, air freshener, and a microprocessor ...

Here in this article I am sharing a DIY guide to make a simple Raspberry pi and PIR sensor based motion detector alarm which will turn on the buzzer when the PIR sensor detects any human movement in ...

Although IP cameras are ideal for Frigate, not everybody has a dedicated security camera lying around. Fortunately, there are ...

In this example, the green polygon indicates the only area within which the newly refined Azure motion-detection service will operate. (Via Microsoft) Microsoft has upgraded the motion-detection ...
