Photocells

Photocells are optical protection devices that detect that there is something between the transmitter and the receiver / reflector by interrupting the light beam (infrared). No matter what it is, everything is detected. The disadvantage, however, is that a photocell only checks at the height at which it is fixed. Even bad weather (rain / fog) and pollution can ensure that a photocell does not function optimally.
