Milk is a perishable product, and even the expiration date mark has not turned sour. The results are not American, but does the US throw away about 20% of all dairy products. And this can only be determined in the packaging.
Please look into this issue with the University of New South Wales (UNSW) Sydney. Using a VibMilk smartphone can benefit from the gadget’s built-in vibration feature without the need to close the lid.
The technology is based on the fact that its physical characteristics of the properties change. For the first time, the maximum size is 6.6, and in the previous version it was 4.4, and this is the case when you need to eat according to the state of the milk for vibration. The vibration is activated by the smartphone, and the operating signal is activated by the nerve measuring unit (IMU), which is based on learning algorithms that test one of the pH levels of the dairy product being tested.
