Cas #1: "Shadow Paralysis" of Solar-Powered Units

Histoire utilisateur: A user installed a solar+battery WiFi level meter on a rooftop tank. It worked fine for the first month. But after winter began, the device frequently went offline. Inspection revealed that due to the lower winter sun angle, the tank's structural elements cast shadows on the solar panel, drastically reducing charging efficiency.

Leçon: Beaucoup "solar-powered" products only consider theoretical peak power, ignoring actual site-specific sunlight conditions.

Cas #2: "Lost Connection Through One Floor"

Histoire utilisateur: A user installed a level meter on a 4th-floor rooftop tank. Après l’installation, signal strength was only 1 bar, and the device constantly disconnected. Two concrete floors severely attenuated the WiFi signal.

Leçon: 2.4GHz WiFi signal attenuation through concrete floors can reach 15-20dB per floor.
Cas #3: "Deadlock Readings" from Probe Scaling

Histoire utilisateur: A food processing plant installed a submersible pressure level meter in a sewage tank. Après 3 mois, readings stopped updating even when levels changed significantly. Inspection revealed a thick layer of biofilm on the probe surface.

Leçon: Impurities and microorganisms in sewage form biofilms on contact-type probes, obstructing pressure transmission.
Cas #4: La gêne du soudain "Mort par batterie"

Histoire utilisateur: A property installed a battery-powered level meter on a rooftop tank. One night, the property received tenant complaints of "no water." Investigation revealed the level meter had been offline for days due to battery depletion.

Leçon: Users cannot reliably remember to change batteries. Devices must display real-time battery levels and proactively push low-battery alerts.
