Elecrow “All-in-One Starter Kit for ESP32-P4” is an open-source learning and prototyping platform based on the ESP32-P4 ...

Abstract: Passive infrared (PIR) sensors are widely used in motion sensing and lighting control. However, stationary occupants always trigger false-negative detects of PIR sensors and result in ...

The PIR library implements a class to monitor 1 or more PIR sensors. The library supports default 8 PIR sensors per object, which typically are added in setup(). It is possible to add a sensor (pin) ...

In modern large-scale combat operations (LSCO), the sheer volume of data from intelligence collection sensors overwhelms division and corps G2s, making it difficult to distinguish critical information ...

The library gives control over up to 16 parallel working PIR devices over I2C. The idea for this library came up in a discussion about how to fully cover an area with PIR sensors without blind spots ...

When it comes to modern electronics, the word “smart” seems to apply to almost every kind of device on the market, especially building automation products such as motion sensors and consumer products ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...

The FP1E’s millimeter wave technology provides for a much more nuanced look at whether a room is occupied or not, but you’ll need one of Aqara’s Zigbee or Matter smart home hubs to use it. Whatever ...

The first thing to know about buying a digital camera in 2024 is that it's virtually impossible to buy a bad one. You probably have a great camera in your hand right now. For many people, a smartphone ...

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) ...
