The ESP32 keeps finding new jobs in my house.

Connecting sensors to Arduino opens up a vast array of possibilities for hobbyists and professionals alike, transforming ideas into functional prototypes and projects. Whether you want to measure ...

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) ...

Passive infrared (PIR) sensors are experiencing sustained growth in 2026. This is driven largely by the expansion of smart home technology, building automation, and energy-conscious design. Once ...

Murata SMD TYPE IRS-D200ST00R1 is one of the world’s smallest PIR motion sensors at just 6 x 6 mm in size and with a 2.6 mm thickness. Its name implies, it’s a reflowable SMD component, which ...

This study investigates the optimization of Fresnel lens designs using Zemax software, with a focus on minimizing beam divergence by controlling the output spot diameter on the image plane. Global and ...

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 ...

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) ...

Hello Hackers! Today we have a really interesting topic. Searching the internet, I didn't find any simple solution on "How to read data from car parking sensors," so I decided to write a short and ...
