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, ...
This Arduino library provides a convenient and easy-to-use interface for the PH4502C sensor, allowing you to effortlessly integrate it into your Arduino projects. The PH4502C sensor is a ...
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 ...
