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.

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

Third Reality has introduced the Motion Sensor R1, a device designed to improve motion detection in smart homes. This is a PIR based motion sensor, so uses passive infrared to detect motion. PIR ...

Bermuda enables device proximity in a room without using any trackers or apps. Using an ESP32, it works as a Bluetooth proxy, ...

A new motion sensor incorporates micromachined thermal transistors to facilitate human presence and motion detection in security systems, home automation equipment, and Internet of Things (IoT) ...

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a ...

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal. PIR ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. You’ve probably seen them—sensors watching from the corners of ...

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object being ...

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 ...
