A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.

IKEA has launched its new Gömpyssling LED light with sensor. It's a motion-activated light which automatically switches on when you open a cupboard or step into a space, then turns itself off after ...

Abstract: This article introduces an inexpensive Wiegand-sensor-based rotary encoder that avoids rotating magnets and is suitable for electrical-drive applications. So far, Wiegand-sensor-based ...

Need a Hall sensor? A strip of copper, a strong magnet, and an LM358 are all you need to explore the Hall effect hands-on. This experimental setup turns microvolt signals into measurable millivolt ...

Every illusion has a backstage crew. New research shows the brain’s own “puppet strings”—special neurons that quietly tug our perception—help us see edges and shapes that don’t actually exist. When ...

Radar sensors have recently been explored in the industrial and consumer Internet of Things (IoT). However, such applications often require self-sustainable or untethered operations, which are at odds ...

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 ...

“Reading the claims of the ‘961 patent, the Federal Circuit noted that the claim language did not require the claimed reflective layers to be epitaxial.” On October 16, the U.S. Court of Appeals for ...

Engineers have worked out how to give robots complex instructions without electricity for the first time which could free up more space in the robotic ‘brain’ for them to ‘think’. Mimicking how some ...

(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 ...
