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 ...

Melexis announced the MLX90514, a dual-input inductive sensor IC that simultaneously processes signals from two sets of coils ...

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 ...

Gesture-controlled gadgets were all the rage at CES back in January. I’m still not convinced it’s a good way to change TV channels, but it can’t hurt to learn how to program for a motion sensor.

Melexis has brought out a dual-input inductive sensor integrated circuit (IC). The device simultaneously processes signals from two sets of coils to compute differential or vernier angles on-chip.

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 ...
