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

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 ...

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

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 ...

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

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 ...

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