Project Summary:

To help electronic DIY hobbyists, will show you how to use Temperature Detecting Heating Control System with Arduino Mega2560.

Full Project:

The temperature detecting heating control system works with DC5V voltage. This system uses DS18B20 temperature detection chip as the external detection equipment.
It works according to the external temperature collected by DS18B20. The system can make the heater work according to the temperature which has been setted. When the actual temperature is lower than the setting temperature, the heater begins to heat to make the temperature go up. When the heating temperature is not lower than the setting temperature, the heater stops working, the buzzer will alarm.
