The sensitivity of the proximity sensor circuit can be adjusted with P1 for the desired “distance”. One of its obvious uses is to open a door automatically. For this the sensor must be placed on the ...

Microcontrollers come in all sorts and sizes, and it’s very tempting to use them everywhere. If you are in a plan to build your own Vending Machine, probably you need a microcontroller-compatible Drop ...

Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have created the world's first all-integrated sensor circuit based on ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

This dual-slope temperature sensor combines one negative-sloped and one positive-sloped temp sensor to create a V-shaped output, which can be used to compensate for a dual-temperature-coefficient ...

Here’s your useful and beautiful circuit for the day — [New Pew]’s vibration sensor takes manual control of the flip-flop inside a 555 timer and lights an LED in response. Use it to detect those ...

Sony just introduced its first 200MP smartphone camera sensor, and yes, it’s called the LYT-901. If you’ve been following camera tech leaks over the past few weeks, this name might feel familiar. It ...

(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 ...
