This compact mains voltage sensor is intended to monitor and signal to another circuit, for instance a microcontroller, about the presence and/or absence of the ac mains voltage. For this task, a ...

In Part 1, we covered the basics ofsensors and the characteristics youmust keep in mind when using them in designs. However, there isan enormous range of specialist sensors developed for ...

Here we designed a simple non contact tachometer using microcontroller which can measure speed with an accuracy of 1 rev/sec. Here we design a simple non-contact tachometer using microcontroller, ...

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 ...

These steps are thenrepeated until the reading is correct at the mid and max values. Thisis usually necessary because the gain and offset interact, that is,adjusting ...
