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.
