The project is based on the Microchip MCP9701 Active Temperature Sensor. This sensor is interfaced with the Arduino MEGA that supplies it and reads its output voltage.
Learn how to use temperature sensor with Arduino, how to connect DS18B20 temperature sensor to Arduino, how to program Arduino step by step. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with Arduino.
The DS18B20 temperature sensors have been divided into 4 buses, as two external sensors are used, making it easier to connect them to separate Arduino outlets and, in the event of a sensor drop, it is easier to replace as it does not paralyze the functionality of the system.
