But like I said, it's a cool project. I've thought about building an ultrasonic water level sensor, connected to an ESP32 or Pi Zero to report water levels to... something TBD.

Project Overview This project implements a smart water pump control system using an Arduino Uno and an ultrasonic sensor (HC-SR04). It automates the process of filling a water tank by turning the pump ...

Now with a new ultrasonic sensor developed by Centre for Development of Advanced Computing (C-DAC), the KWA is getting updates about water level at regular intervals via SMSs.
