There is no particular input for temperature sensors in Node. Four analog inputs are available. Any of these can be used to measure the temperature sensor resistance. But the single-ended (AI 1, AI 2) is more accurate than the differential inputs (AI 3, AI 4) because the voltage difference is less. A simple circuit with an extra resistor for voltage dividing has to be implemented externally. For details about using temperature sensors please check our System integration guide.
A voltage divider is needed when the Analog In needs to be calibrated. This is required for adjusting the measuring range when using a temperature sensor.
The image below depicts how to connect an RTD sensor resistance using the single-ended analog input.
Attention
The ADC value is scaled to 16 bit since firmware v5.0.
The internal resistance R i of the single-ended analog input is 20.4 kΩ and it is connected in parallel to the RTD sensor.
