Abstract

The invention concerns a sensor device, a method, computer and computer program product for configuring the sensor device, a configuring apparatus as well as a method, computer program and computer program code for providing a reporting configuration to a sensor device. The configuring apparatus (26) comprises a signal emitter (28), actuator (44) and a control unit (46) controlling the actuator (44) to vary a physical property of the signal emitter (42) for modulating network access data comprising access point accessing data as a variation of the physical property for conveying to the sensor device (10). The sensor device comprises a sensing unit (12) measuring the physical property (T), a reporting unit reporting measurement data of the physical property, a decoding unit decoding the network access data and a wireless communication unit that connects to a wireless access point (16) of a sensor network (14) using the access point accessing data.
