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.

Thermistors and silicon temperature sensors are widely used forms of analog-output temperature sensors. A silicon temperature sensor is a far better choice than a thermistor when a linear relationship ...

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 ...

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 ...

Most electronic engineers know that a transistor’s base-emitter voltage (V BE) has a temperature coefficient (TC) of about -2 mV/°C. However, for precision temperature sensors, “about” isn’t good ...

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 ...

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 has officially introduced the Lytia 901, marking its long-awaited entry into the 200MP smartphone camera segment. The ...
