Answer:

One of the most critical design objectives for the LeakAlertor was simplicity of installation and use.
Achieving that objective without any user setup or calibration required developing a unique sensor
technology and a correspondingly complex mathematical process that would allow the product to be
placed on virtually any tank and flapper based toilet (there are hundreds of different models),
accounting for dozens of different types of fill valves, flappers, and variations in water pressure
(even on the same toilet), while simultaneously ignoring external noise, incidental bathroom
“disturbances” (use your imagination!), and all kinds of interference.
