How the Kisan Mitra Chhadi works, from its 5 to 15-metre detection range to the vibration alert that could help farmers avoid ...

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 ...

Sensors monitoring mechanical and biological systems must often scavenge power from the thing being sensed. The oscillator circuits shown here let you operate those sensors. Sensor circuits that ...

(TNS) — The state of Connecticut is testing new vehicle technology designed to eliminate impaired driving. The Driver Alcohol Detection System for Safety vehicle measures carbon dioxide and ethanol ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...
