2.4.4 Sensors

KNX sensors are an important part of the KNX system. Sensors form the interface
between the user or the physical size and the KNX bus. Using switch sensors, the user
calls up previously configured functions such as arming/deactivating the system, switching
the lighting, moving the shutters, movement/presence detected, switching on the siren.
They convert physical variables into electrical values which are then sent on the bus as a
telegram.

The switch sensors form a group of sensors. The switch sensors are then subdivided into:
simple push-buttons, group push-buttons, switch sensors, room temperature thermostats,
multifunction sensors.

Example 1: A simple push-button in the bedroom is installed so that it can be operated
from the bed in an emergency. It is set in the parameters that the rocker triggers an alarm
once it has been pressed for 3 s to avoid incorrect operation. The reset is then carried out
e.g. on a multifunction switch sensor, whose operation is protected by entering a PIN
code.
