A common sight in ‘smart homes’, door sensors allow you to detect whether a door is closed or open, enabling the triggering of specific events. Unfortunately, most solutions for these ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, ...

Researchers developed a single-use sensor strip that can be used with a circuit board to detect cerebrospinal fluid leaks. They collected nine clinical samples and introduced the test fluid into a ...

Aqara is introducing a new presence sensor that is a natural addition for HomeKit users who want reliable automations without the need for a camera. The new Aqara FP300 combines mmWave presence ...

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display ...

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 ...

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) ...

AUSTIN, Texas — Prometheus Security Group Global, a Zero Trust physical security provider, has been granted a U.S. patent for a novel method of securing legacy analog circuits in physical security ...

Engineers have made bacteria to produce hyperspectral signals that can be detected as far as 90 meters away. Their work could lead to the development of bacterial sensors for agricultural and other ...

Bacteria can be engineered to sense a variety of molecules, such as pollutants or soil nutrients. In most cases, however, these signals can only be detected by looking at the cells under a microscope ...
