Celsius-to-digital thermometer works with remote sensor


Posted on Jan 13, 2013

You can use a single-supply system to precisely measure the temperature at a remote location with less than 1°C error over a 0 to 100°C range (Figure 1). The circuit includes T1, a low-cost AD590 temperature sensor; IC1, an AD8541 rail-to-rail amplifier; four resistors; a trimming potentiometer; and an ADC. You can omit the ADC if you need an analog output. You could replace the trimming potentiometer with an AD8400 or AD5273 digital potentiometer for easier calibration.
