NFC Plumbing Control Sensing for Remote Water Measurement

The patent replaces traditional mechanical thermometers and pressure gauges with electronic sensors that communicate wirelessly. Temperature sensors (e.g., thermistors, RTDs) and pressure sensors (e.g., strain gauge sensors, piezoelectric sensors) are installed within the PCD, eliminating the need for mechanical contact measurements at distant locations. The sensors transmit data wirelessly to remote displays, simplifying operation and eliminating disassembly requirements.

The patent introduces wireless communication modules and microcontrollers as intermediaries between the sensors and the user interface. The microcontroller reads sensor data and transmits it via wireless communication (e.g., Bluetooth, Wi-Fi) to a remote display device, allowing measurements to be viewed at convenient locations without physically accessing the PCD interior or measurement points.

The patent implements energy harvesting mechanisms where the PCD itself generates or captures energy to power the sensors. Examples include piezoelectric elements that convert water pressure fluctuations into electrical energy, or thermoelectric generators that utilize temperature differences between hot and cold water streams. This self-powered approach eliminates the need for external power connections while maintaining continuous sensor operation.

The patent employs periodic measurement and wireless transmission of sensor data, allowing the system to operate in low-power mode. Sensors take measurements at intervals rather than continuously, and wireless transmission occurs periodically when data needs to be updated. This reduces overall power consumption, making the system viable even with limited energy harvesting capacity.

The patent creates a universal remote interface that can control and monitor multiple PCDs from a single location. The wireless communication system allows a user to access temperature, pressure, and flow data from various PCDs throughout the building via a smartphone or computer interface, eliminating the need to physically visit each isolated PCD location for monitoring or adjustment.

The patent implements real-time feedback loops where sensor data is continuously monitored and displayed remotely. Users can observe the effects of adjustments in real-time without leaving their workspace, allowing for rapid iteration and optimization of plumbing parameters. The system provides immediate feedback on temperature, pressure, and flow changes, enabling efficient troubleshooting and tuning.
