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

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

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Abstract: An important issue faced while employing Pyroelectric InfraRed (PIR) sensors in an outdoor Wireless Sensor Network (WSN) deployment for intrusion detection, is that the output of the PIR ...

While fluorophore-biomacromolecule systems are relatively well known, afterglow luminophore-biomacromolecule conjugates/complexes are rarely studied. Here, the authors report the development of a ...

This research is aimed to explore the efficacy and comparison of low-cost light sensor measurements for agricultural applications. For this reason, TSL2561, BH1750, and TEMT6000, low-cost light ...

The SHT3x family of sensors should work up to 1 MHz I2C. This library should also work for SHT30 and SHT35 but these are not tested yet. Sometimes you need to control more devices than possible with ...

Abstract: During war fields and natural disasters like earthquakes, rescue crews struggle to find victims due to people being buried under debris, stuck in inaccessible locations, or unseen by rescue ...
