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 ...

The P0463 code indicates that your car’s engine control module (ECM) is receiving a voltage signal from the fuel level sensor ...

This article explains an upgraded smart solid-state AC switch system that uses microwave Doppler radar instead of traditional ...

The P0118 code means that the engine control module (ECM) has detected a voltage signal that’s too high from the engine ...

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 ...

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 ...

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 ...

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 ...

With a pixel array format that delivers both high resolution and high sensitivity, the new LYTIA 901 sensor achieves ...
