Recently, many netizens have forwarded such message on microblog that there are blind spots in parking sensor. One netizen said that
" My car often cannot detect the low-level shoulders and always hits the curb kerb." So is it true that parking sensors have some blind spots? To solve this question, CCTV has made a test for the parking sensors available in the market, both aftersales market or OEM market as below:

As a conclusion of the video above, an object can’t be detected until its height is 43cm. As 43cm is equal to 17 inch, and when a kid kneels down his/her height will be equal to a third of his/her total height, thus, a kid can’t be detected by the parking sensor when he kneels down until he is 51 inch origin height which belongs to an 8 year old boy or girl (see the list below to check up the average height of a child), source from link:

Your child's size and growth timeline

Lots of parents wonder whether their child is bigger or smaller than other kids the same age.
To give you a benchmark, here are the values from the 25th percentile to the 75th percentile for weight and height – meaning that half of kids fall within these ranges. A quarter of kids fall above these numbers and a quarter of kids below them.
At each well-child visit, the doctor will weigh and measure your child and tell you his height and weight percentiles. (You can also compute them yourself, using our Growth Percentile Calculator.) Talk with the doctor if you have any concerns about your child's growth.
The data below comes from the World Health Organization for children under age 2 and the U.S. Centers for Disease Control and Prevention for children age 2 and older.
