Abstract:
1. A control system for controlling at least one environmental parameter in an operating area in response to sensor signals, the system comprising a central control unit, actuators and mobile sensor units, wherein: the central control unit communicates with the actuators and the sensor units, and is configured to send control signals to the actuators based on the sensor signals from the sensor units, the actuators are placed in the operating area or in a vicinity to the operating area and are configured to receive the control signals from the central control unit and operate to affect the at least one environmental parameter in the operating area, the mobile sensor units being configured to measure the at least one environmental parameter in the operating area when the sensor units are located in said operating area, characterized in, that the control system also comprises at least one, preferably a plurality, of communication nodes which are placed in the operating area, wherein each one of the communication nodes is configured to mediate signals between the sensor units and the central control unit in a monitoring area by wirelessly receiving the sensor signals from the sensor units located within the monitoring area and forwarding the sensor signals to the central control unit, wherein the monitoring area of at least one communication node is defined by the signal coverage of said at least one communication node.
