How to set up a vacuum sensor (festo spea 8001443)
A vacuum sensor is often used in a pneumatic circuits to provide an analog signal determined by the vacuum strength.
Step 1: Wiring the sensor
Step 2: The pneumatic circuit
By connecting the black wire to an analog input of the PLC, the analog value of the sensor can be read into the I/O of an universal robot.
Using a vacuum sensor along with suction cups is good for feedback in a pneumatic system. You can find what else is needed to build a pneumatic system like this in the link below.

Place the vacuum sensor in series with the vacuum generator to ensure that the sensor can measure the vacuum properly.
Step 3: Program
To read out the analog value of the sensor the following code line can be used:
robot.getAnalogInput0() #replace number with the AI number where the sensor is connected.
