I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

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.

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.
