Introduction: Arduino Temperature Controller
Control the temperature of your aquarium or greenhouse
The sensor (DS18b20) measures the temperature of your aquarium or greenhouse.
The display shows the current temperature and the status: cooling or heating.
<25°C -> Relay Channel 1 active -> heating
>25°C -> Relay Channel 2 active -> cooling
You can easily change the temperature values in the arduino code.
