All componentsof the pneumatic system are standard products with no modifications.Figure 15 shows the floor location sensors used to signal the control measures when the cart is atthe desired floor. They are optical gate switches through which a metal tab on the elevator carpasses. Figure 16 shows the limit switches that are installed at the top and bottom of the mainrail on each side of the elevator support shaft. These limit switches are fed to the supervisorycontrol so it can automatically stop the motor drive in the event a user tries to move a car beyondsafe limits. Figure 15.

In orderto provide these features, a Raspberry Pi model B+ was used, together with a small seven-inchmonitor. Data from the Arduino was transferred via the serial interface over a standard USBport to the Raspberry Pi.
