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 ...

To be honest, I didn’t know we could do this yet. Welcome to the future, Paul. SCiO is a miniaturized near-infrared spectrometer, which detects the molecular signature of things. It was Kickstarted a ...

Jacob Kastrenakes is The Verge’s executive editor. He has covered tech, policy, and online creators for over a decade. Philips Hue has a new accessory that’ll make it even easier to automate the ...

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 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 ...
