It is a project of a thermometer to measure temperature of water on the stove and boiler.
The device is based on Atmega8 microcontroller, the display applied has RGB backlight. Control of illumination in green is achieved by Adc photoresistor and Atmega PWM (when it is bright in the room, it dims the display). Red light is used together with the buzzer when the temperature exceeds 88 degrees Celsius. Temperature sensors are DS18B20.
The program was written for CO installation, but it can be improved to measure water heated by the solar.
The program was written in Bascom. The buttons are used for mode Co and Solar switching.
