[size=4]The car trunk induction opening function is very popular. Can anyone help explain the principle? I only know that it is part of the PKE (keyless entry system). What sensor does the induction s...
The first step is to realize energy collection. From the curve data in [url=https://bbs.eeworld.com.cn/thread-413365-1-1.html]https://bbs.eeworld.com.cn/thread-413365-1-1.html[/url], we can know that ...
The rules do not allow short circuits. I don't know why the wire can be pulled even though it is smaller than the gap, resulting in a direct short circuit.
The original setup either pushed the existin...
I tried to click on it and found that I could still participate in the lottery if I didn’t win that time, so I tried it and won. I was so lucky. :loveliness::)...
