Question: “Do you know how old the milk or orange juice in your refrigerator is?”

Another Question: “How long has the milk been outside of the fridge?”

This project solves all of these problems!
It is a device one can place on a bottle and push a button once placed in the fridge.

1. The device will remind you how many days left until fresh things become not so fresh (usually 3 days).

2. Saves energy with a light sensor, when the door is closed.

3. Reminds you when you leave the bottle outside of the fridge using a temperature sensor.
