Want to make water for your chimarrao and wonder if your kettle has reached your sweet-spot temperature? This is a arduino based battery powered water temperature sensor to put into your kettle. As soon as the set temperature is reached, the sensor makes noise and the green LED lights up.
- 1 x Arduino Nano
- 1 x DS18B20 waterproof temperature sensor
- 1 x 1/2 or 1/4 sized solderable breadboard (the STL is made for 1/4 size)
- 3 x 150 Ohm resistors
- 1 x green LED
- 2 x red LED
- 1 x battery holder for 4xAA or 4xAAA batteries
- 1 x switch
- 1 x piezo buzzer
- cables
When you solder the resistors directly to the LED's you get along with a 1/4 sized breadboard. Other than that, just put together, put everything into the box and you are ready to go.
I used superglue extensively when putting everything into the 3d printed box.
This was made with simplicity in mind to keep usage, code and assembly as simple as possible. Change min_temp and max_temp to adjust to your tastiest temperature.
