You are totally right, I found the problem, that is my sensor connection's problem, 3 of the wires that hook on the sensor had been combined into one jumper cable with 3 pins on it, that means I cannot change the sequences of the pins (V G Vout), so that's why I connected wrong on the project board, because the project board required the sequence of Black, Yellow and Red, but as you can see in #45, mine was Black Red and Yellow because the wires are all in one, so I have to cut and solder it.
