Abstract: In-situ fluorimeters and methods and systems for collecting and analyzing sensor data to predict water source contamination are provided. In one embodiment, a method is provided that includes receiving sensor data regarding a water source. Changepoints may then be calculated within the sensor data and the sensor data may be split into intervals at the changepoints. A machine learning model may then be used to classify the intervals and a predicted contamination event for the water source may be identified based on the classified intervals. In another embodiment, an in-situ fluorimeter is provided. The in-situ fluorimeter comprises one or more UV LEDs centered around a pre-set excitation wavelength (e.g., a TLF excitation wavelength), a bandpass filter, a lens, a photodiode system, a machine learning platform; and an alarm triggered by contamination events, wherein the alarm is calibrated through the machine learning system.

Abstract: Methods and systems for collecting and analyzing sensor data to predict water fixture failure and water consumption are provided. In one embodiment, a method is provided that includes receiving sensor data regarding a water fixture. Changepoints may then be calculated within the sensor data and the sensor data may be split into intervals at the changepoints. A machine learning model may then be used to classify the intervals and a status of the water fixture and water consumption may be identified based on the classified intervals.

Abstract: Microcomputer with a sleep mode system uses a non-volatile memory stack for saving system variables, then switches the microcomputer completely off to go into sleep-mode. In sleep-mode, the microcomputer sleep mode system uses a low powered clock and sensors to trigger time events and device events that power up the microcomputer when needed. When in awake-mode, the microcomputer logs any data from connected device(s). The microcomputer turns on an internet radio and transmits data logged, updates its clock time and receives any configuration updates before powering back down into sleep-mode.
