- Each sensor takes seven ultrasonic readings hourly, keeps the middle value, then sleeps.
Field notes
The described sensor wakes hourly, takes seven ultrasonic measurements and uses the middle reading before sending it to a gateway over 4G. The page says the gateway stores readings when the signal drops and forwards them on a later cycle. Dashboard examples are explicitly labeled demo data; the homepage also describes QR labels for checking a tank's name, photo and level without an app or login.
