I built a ghost-proof ESP32-powered presence sensor and here's how it works
Bermuda enables device proximity in a room without using any trackers or apps. Using an ESP32, it works as a Bluetooth proxy, ...
Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...
The Aqara FP300 is a battery-powered presence sensor with Thread and mmWave radar, giving HomeKit precise motion and environmental detection.
DMP is pleased to introduce the 1122 Wireless PIR (Passive Infrared) Motion Detector. Available now for order, the 1122 comes in a sleek tear-drop shape that has all of the functionality of the 1121 ...
It’s really hard to overstate how awesome ESP8266 development boards like the Wemos D1 Mini really are. For literally a couple of dollars you can get a decently powerful Wi-Fi enabled microcontroller ...
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 ...
TAKEX PIR-T40NAM is an indoor/outdoor 135 feet/40 meter long range vertical curtain passive infrared utilizing triple mirror technology and signal processing for accurate detection and small animal ...
