3.2.2 Pressure Sensor
1. Voltage Measuring Point
When the color of harness is not as mentioned above, find the measuring point by following
procedure.
1. Black is GND.
2. Find DC5V line.
3. The remained wire is the sensing section.
(For the same pressure, higher output voltage can be detected with low-pressure sensor,
while lower output voltage detected with high pressure sensor.)
