Arduino temperature read and relay control

Basic temperature monitoring and management with Arduino

This code reads temperature from a temperature sensor and then control a relay (assumed a heater).

Serial commands:

Get temperature

• Command T
• Returns all the connected sensors temperatures

Set temperature

• Command S[H|L]
• Allows to set high temp with S (ex. S1H 22.1)
• Set low temp (ex. S1L 20.5)

This is made with Arduino Uno board, DS18B20 Temperature sensors and a relay board.
