Abstract: The sensor (8) includes control means (12) configured to switch the sensor (8) in the sleep mode when the sensor is in an active mode and when receiving a sleep mode signal. The sensor is configured to take measurements and to send measurements to a gateway in the active mode, and is configured to stop taking measurements and disconnect from the gateway in the sleep mode.

Abstract: A Sensor (2) is proposed. The sensor (2) includes a memory (5) and a control means (6). The control means (6) is configured to: store in the memory (5) connection parameters (5a), switch the sensor (2) in a sleep mode when connection parameters (5a) are stored in the memory (5) and when receiving a sleep mode signal, and start the sensor at the reception of a start signal (S1) by the control means of the sensor (2).

The sensor is configured to take measurements and to send measurements to a gateway in the active mode, and is configured to stop taking measurements and disconnect from the gateway in the sleep mode.

Abstract: A processor-implemented method for vector analysis to extract a speed of a rotating part of a machine is provided. The processor-implemented method including receiving, by a processor, two channel synchronous signals derived from at least two sensors coupled to the machine and positioned 90° with respect to each other; determining, by the processor, a plurality of vector angles for a plurality of samples from the two channel synchronous signals to identify a period; determining, by the processor, a time difference based on a sample rate and a number of the plurality of samples that are within the period; determining, by the processor, the speed based on a time difference. A system for carrying out the method is also provided.
