Digital remote thermometer(FDD5/JDD5) circuit diagram

Published:2011/4/8 3:02:00 Author:Rebekka | Keyword: Digital remote thermometer

Transmitter circuit: Temperature detection circuit is composed of integrated temperature sensor AD590. It can convert temperature changes into output current changes. The output current of AD590 should be proportional to measured temperature. As the temperature increases, the output current 1μA / K a constant rate should increase. When the output current pass RP2, it will form into voltage drop on its upper. After being amplified by the voltage amplifier, the voltage will be the voltage of frequency converter.   (View)
