The simplest temperature test circuit composed of AD590 is shown in the figure. AD590 switches the temperature under test into current, which makes the microamp meter deflect. After the meter is marked, it can be used as the analog thermometer. To avoid the disturbance from the outside, the outgoing line should be the double stranded wire(stranded wire for short), and its length could be several hundred.
