Assignee: EVERACTIVE, INC.
Field: Measurement (Instruments)
Classification: CPC F  G | IPC F  G

Claim 17:
18. A steam trap monitor, comprising:
a plurality of temperature sensors configured to generate sensor signals representing a steam temperature and a condensate temperature associated with a steam trap;
one or more transmitters configured to wirelessly transmit sensor data representing the sensor signals to a remote device;
a wakeup receiver configured to receive a wakeup message from the remote device;
control circuitry configured to control operation of the one or more transmitters, and to convert the sensor signals to the sensor data, the sensor data comprising first time series data representing the steam temperature and second time series data representing the condensate temperature, wherein the control circuitry is further configured to wake up from a low-power mode in response to the wakeup message to take readings of the sensor signals, control operation of the one or more transmitters, and convert the sensor signals to the sensor data;
a thermo-electric generator configured to harvest heat energy from an environment in which the steam trap monitor is deployed;
an energy harvesting device configured to harvest a different type of energy than heat energy from the environment;
an energy storage device configured to store energy derived from a combination of the heat energy and the different type of energy; and
power management circuitry configured to control the storing of the energy derived from the combination of the heat energy and the different type of energy by the energy storage device.
