4 wires going out of the board they are on:
|
|
- Red - power, at least 2v to see anything happen, not sure of optimal range.
|
|
- Black - GND
|
|
- White - data out for 1 of the sensors
|
|
- Although there is a difference in voltage state of this wire when the sensor is triggered, it is a very low difference.
|
|
- When powered by 3.3V, it goes from 80mV to 240mV
|
|
- Green - data out for the other sensor
|
|
- This wire has a much bigger voltage difference when the sensor is triggered.
|
|
- When powered by 3.3V, it goes from 1.92 to 3.32
