The pins labeled A0 - A5 on the Arduino are special pins that when read with the analogRead () function will return the value from 0 to 1023 where the input voltage is from 0V to 5V. It works by measuring the ambient temperature using a thermal sensor and controlling the heating or cooling mechanism so as to maintain the set . 1. Place the temperature sensor on the breadboard in row E, as shown. C/C++. This module has both digital and analog outputs, there's a potentiometer to adjust the detection threshold on the digital interface. The middle wire will go to A1 (analog pin 1). Read a1 Music wire of the temperature sensor is connected to the a1 pin of the arduino, so it will arduino will read that the data from the temperature sensor now the voltage of the temperature sensor is proportional to the change in temperature in degree celsius. A quick look on eBay suggests they are going for about $0.99 each in the USA and around 0.50 in the UK. Gnd to Gnd. Created by Mirko Pavleski, the "room comfort thermometer" uses LEDs to indicate its reading. You can choose one of them, depending on your needs Step 1: Build Circuit. We used A0 for this project.
