The ultrasonic sensor can measure distances in centimeters and inches. It can measure from 0 to 2.5 meters, with a precision of 3 cm. It provides good readings in sensing large-sized objects with hard surfaces, but has more difficulties reading reflections from soft, curved, thin or small objects.
So how long will thawed breast milk last? If you let the breast milk thaw out in the fridge, you can keep it in the fridge up to 24 hours after it has finished thawing. (Note that it can take around 12 hours to thaw depending on how much milk is in the container and how cold your fridge is). If you warmed the thawed breast milk, do not try to hang on to it. Warmed milk is far more likely to have been exposed to bacterial growth.
You can thaw frozen condensed milk overnight in the refrigerator, and then use as directed. Alternatively, warming the condensed milk in a water bath will help to thaw it. Condensed milk can be frozen for up to three months without any noticeable flavor or texture changes, so long as the container is tightly sealed.
