Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

Ultra simple circuit of the tilt sensor alarm presented here can be fabricated using readily available inexpensive components. The circuit is a true transistor based design. Home made Tilt sensor for ...

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 ...

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 ...

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 ...

A sensor signal conditioner (SSC) is an integrated circuit that improves — or conditions — the signal coming from a sensor to reduce noise. The SSC also converts the signal from analog to digital ...

A team of engineers at the University of California San Diego has developed an electronic sticker that can monitor a person's ...
