Method and system of a networked scent diffusion device

The abstract describes a system for remotely controlling scent diffusion to achieve a target scent level. However, the specific claims only detail a method for determining the liquid fill level within such a device. This is done by taking sensor readings, such as voltage, and processing them to estimate how much scent remains, possibly by detecting a magnet's position.

Why it matters: Incremental improvements in low-cost, low-power magnetic and voltage sensors since 2023 could make the claimed fill-level detection method more reliable and cheaper to implement. However, the method itself remains a basic thresholding approach.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateElectronics, sensors, magnet, communication, software logic
