The pressure sensor doesn't know how the 4 lines are connected. How do you determine what the 4 line is? 5
The general color classification of sensors is green signal + white signal red excitation + Black excitation -Of course, there is also different from this definition.But it can be measured by measuring the resistance between two wires. Usually the input impedance is about 385 ohms, and the output impedance is about 350 ohms.There are signs on the general sensor.Not really, one by one test, the short test will not burn the sensor
Generally I am a direct experiment, a good circuit board test, I do not know what sensor you use, usually will not burn the sensor. Of course, to master the basic common sense, the general red line is the power supply, black is power negative (or dark line); signal you try it. No, you see the sensor type
2 follow the power supply, 2 follow the signal
