Abstract: A multi-function acquisition device comprising a connector having two connection terminals, and an electronic circuit that comprises an acquisition circuit configured for enabling the digital conversion of analogic signals from a sensor, and the memorization of the digitized signals in a memory; a harvesting circuit configured for enabling the transmission of data stored in the memory to a harvesting device; a charging circuit configured for enabling the charging of a battery with the power provided by a powering device. A control unit controls the activation of the acquisition circuit, the activation of the harvesting circuit, and the activation of the charging circuit.

Abstract: A communication system includes a node configured to collect ambient data with a sensor, and a docking station configured to couple to the node and to establish a communication path with the node through only one signal along one or two wires. The node includes a first module configured to use a first data communication protocol for receiving commands from the docking station along the communication path, and a second module configured to use a second data communication protocol for sending the ambient data to the docking station along the communication path. The first data communication protocol is different from the second data communication protocol, the first data communication protocol is asynchronous and the second data communication protocol is a modified synchronous protocol.
