the ADS122C04 is able to measure the sensor’s resistance very accurately and the Arduino library converts this to temperature using a polynomial equation. PRT sensors can be used to measure temperatures in the range -200°C to +850°C depending on which sensor you choose. The sensors are ...
We even made the breakout 5V compliant, with a 3.3V regulator and level shifting, so you can use it with any for For Arduino or microcontroller. Each order comes with one assembled RTD amplifier breakout board. Also comes with two 2-pin terminal blocks (for connecting to the RTD sensor) ...
