A system that monitors toilets for leaks using in-toilet monitors with pressure sensors that are placed underwater in toilet tanks. Monitors can be dropped into tanks without additional wiring or installation; they may be battery powered and may transmit data wirelessly. Data may be analyzed by a server that detects leaks or other malfunctions. Pressure data may be filtered to remove the effect of barometric pressure, to measure the height of water in the tank. The system may learn the flush pressure change pattern for each toilet; pressure changes that do not match this pattern may indicate problems such as leaks. Data may indicate the type of leak, such as an open flapper or a leaking valve. Toilet monitors may measure temperature, and the system may generate alerts when freezing appears imminent. The system may keep flush counts for each toilet to support maintenance and water consumption measurement.

Toilet monitoring network that detects leaks and flushes

A climate control system that detects presence of a person in a room by analyzing small fluctuations in barometric pressure due to breathing. When the room is occupied, thermostatic control by the occupant may be enabled; when unoccupied, HVAC systems may be set to a low-power state. Barometric data may be processed using a bandpass filter that passes frequencies that correspond to typical human respiration rates. Barometric data may be used to determine when doors or windows are open or closed. Embodiments may connect to property management systems determine whether occupants are expected; when a room unoccupied but an occupant is expected, HVAC systems may be set to a standby state that saves power but allows temperature to return quickly to desired levels when a person enters the room. Occupancy detection may also use data from other sensors such as gas analyzers that detect compounds in exhaled breath.
