1.3.2.4.1.3.4.2.2.1 How to connect a temperature sensor
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.
