2.1.3 Using digital input with a sensor

There are thousands of sensors on the market, e.g. like motion detector,

optical sensors (photoelectric switch), humidity detector, magnetic contact

switch, float switch, .....

In the picture below is used a powered contact sensor on the Barionet, here

is a wiring diagram of this sensor:

The blue and the brown cable are the power cables

of the sensor. In this case the Barionet50 (pin 1+2

of J10) is powering the sensor.

The signal wire of the sensor is connected to input

1 of the Barionet.

Attention

, before doing that make sure the sensor can handle the same

power as the Barionet is using and your PSU is providing enough power for

Ba sensor! The sensor can be powered externally also, in this case it

could make sense to use the same ground as reference for the input signal.
