Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

Module provides integration and flexibility for passive infrared (PIR)-based motion detection applications including customer sensing, lighting control and other energy management purposes. The ...

The Aqara FP300 is a battery-powered presence sensor with Thread and mmWave radar, giving HomeKit precise motion and environmental detection.

Detecting and measuring movement is an essential element for many industrial and commercial IoT applications – from lighting and security to assisted driving. Motion detection systems consist of a ...

Many close-proximity motion detectors use the classic, widely available passive-infrared (PIR) approach, which is effective but has limited sensitivity and adjustability, and can’t “see” through ...

Presence/motion sensors are one of the best ways to make automations feel more natural, but most of them run on batteries and eventually have to be swapped. That’s one of the main reasons I really ...

Researchers designed an IoT network using sound and motion sensors that estimates public space utilization. The ideas can be applied to other IoT sensor networks. Sensor Fusion for Public Space ...

Using the latest Raspberry Pi 4 Model B mini PC, you can easily create a sophisticated security camera system complete with a motion sensor. This setup will automatically send images taken using a ...
