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, ...
If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds ...
Python module for the SparkFun Qwiic PIR - 1 uA (EKMB1107112) and SparkFun Qwiic PIR - 170 uA (EKMC4607112K). This python package is a port of the existing SparkFun Qwiic PIR Arduino Library This ...
Abstract: Pyroelectric infrared (PIR) sensors are much promising for device-free localization (DFL) due to their advantages of lower cost, low power consumption, and privacy protection. Most PIR-based ...
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 ...
While fluorophore-biomacromolecule systems are relatively well known, afterglow luminophore-biomacromolecule conjugates/complexes are rarely studied. Here, the authors report the development of a ...
Abstract: Pyroelectric infrared (PIR) sensors are widely used as a simple but powerful people presence triggers, e.g., automatic lighting systems. In particular, by alternating the effective ...
This is a library for the Arduino IDE that helps interface with ST's VL53L1X time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.
