Here, we designed an analog to digital converter circuit, working as a digital voltmeter using a low power three and half digit A/D converter ICL7107 having internal 7 segment decoders, display ...

The digital voltmeter may be used to measure the thermocouple voltage and determine the temperature of the hot junction in the indium sample. This voltmeter is in parallel with the computer data ...

This digital thermometer circuit diagram uses a common 1N4148 diode as the temperature sensor. The temperature coefficient of the diode, -2 mV/°C is exploited for this application to create an ...
