The main principle of this circuit is to display the digital temperature value. Here, ATmega8 microcontroller is used. The ATmega8 has inbuilt analog to digital converter with six multiplexed channels ...

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 ...

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 ...

Sometimes you need to know what temperature something is, but you don’t quite want to touch it. At times like these, you ...

Designers face many chal lenges when placing thermal-sensing components in embedded systems. The first comes in choosing the temperature sensor. It is often not obvious whether a thermistor, resistive ...

This ESP32-based smart energy monitor can predict your next electricity bill. It tracks voltage, current, temperature, ...

Designers often want to measure the junction temperature of a DC switching power supply. Knowing a system’s junction temperature is an important and basic requirement from safety and failure mode and ...

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 ...
