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

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Just about every “getting started with microcontrollers” kit, Arduino or otherwise, includes an ultrasonic distance sensor module. Given the power of microcontrollers these days, it was only a matter ...

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) ...

When someone hacks together a digital camera with a Raspberry Pi, the limiting factor for serious photography is usually the sensor. No offense to the fine folks at the foundation, but even the “HQ” ...

Raspberry Pi launched a follow-up to its Camera Module 3 with the Camera Module 3 Sensor Assembly. Now, Raspberry Pi users can put the camera sensors into their own custom form factors. The move ...

More efficient, smaller, and lighter traction inverters for EVs can be created by integrating current sensors directly into SiC-based power modules. Silicon Austria Labs (SAL), a power semiconductor ...

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 ...

Why and how indoor air quality is an increasingly important metric. Details of the seven parameters assessed by this all-in-one module. The need for a fan to ensure consistent airflow. Quantitative ...

Abstract: This aim is to provide automatic, efficient and precise lighting and appliance automation with the help of detection through sensors and app controls using IOT. It makes the operation of ...

Modern vehicles rely on a massive amount of electrical systems, sensors, and control modules to keep the wheels turning. Some of those devices are well-known, like your car's main computer or engine ...

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 ...
