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 ...

I wanted to know when my rainwater well is empty and I've read about solutions using ultrasonic sound measurements. So I decided to create something like that for my rainwater well. I chose an ESP32 ...

IoT-Based-Water-Quality-Monitoring-ESP This Arduino-ESP8266 system tracks pH, TDS, flow rate, water level, and temperature using multiple sensors. Data is sent to ThingSpeak for real-time monitoring ...

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

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...

The XBee can detect the water level by testing for a closed circuit between the two electrodes of any sensor module. The water acts as a sort of switch that closes the circuit.

The paper introduces an innovative Internet of Things (IoT)-based scale sensor that measures the water level in the alternate wetting and drying (AWD) system and displays data in the mobile app to ...
