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.
Thawing Chicken. Thaw frozen chicken slowly and safely. It will take anywhere from 24 hours to two days to thaw a whole chicken in the refrigerator, and about 2 to 9 hours for cut-up chicken parts (less for boneless pieces). You can thaw chicken more quickly in a cold water bath or by using the defrost cycle of the microwave.
