In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

The Arduino is a great way for hobbyists and pros alike to experiment with programmable objects, but it can be confusing for beginners without these tools.

Researchers have developed a smart water-spray cooling system for PV panels that activates only when temperatures exceed a ...

A basic building block is often the key to completing an analog signal path in various applications, such as automated test equipment.

Researchers report that lab tests of a new metasurface-based antenna that can harvest 100 microwatts of power, enough to power simple devices, from low power radio waves. This represents an important ...

Raspberry Pi Pico microcontrollers come with a variety of different features for a few bucks, and a few interesting ...

Researchers have uncovered a universal pattern showing how temperature affects life on Earth. Across thousands of species—from microbes to reptiles—performance rises gradually with warming until an ...

Welcome back to air conditioning season, Arizona. Experts are here to settle your yearly fights. This is where you should set ...

In reptiles, a simple temperature change can determine whether an egg develops into a male or female. This process is formally known as temperature-dependent sex determination (TSD), in which the sex ...

A high-tech device that can monitor medication use and compliance has been cleared by the FDA for use with AstraZeneca’s Airsupra and Breztri inhalers. Developed by Australian medtech firm Adherium, ...

Researchers have long known that temperature can determine whether some reptiles develop as male or female, but this process ...

Although it dates back to the early days of the Marconi Company in the 1920s, the Franklin oscillator has remained a relatively obscure circuit, its memory mostly kept alive by ham radio operators ...
