Setup a external temperature sensor
Introduction
This page describes how to setup external Temperature sensor using a Revolution, Revolution Nano, or Sparky2 board, to be used as HoTT sensor.
Two temperature sensor can be connected to a ADC port :
- LM35 sensor, up to around 100°C
- NTC sensor, up to 300°C

Hardware
LM35 sensor
Connections are pretty simple: Gnd, +5V, and analog voltage proportional to the temperature (usually 0.01V/°C) back to the ADC pin.
The sensor can be connected to various ports, according to the board you use. See next part.
NTC sensor
NTC can be connected to the ground or to the 3.3V voltage reference and following settings will be adjusted with the values used.
The sensor can be connected to various ports, according to the board you use. See next part.
