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 ...

This controlled water flow ensures the plant never gets too much or too little. However, since different plants require different amounts of water, you're free to modify the Arduino code's ...

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 water passing through the filter is monitored by a couple of DFRobot TDS modules, a flow meter, and a DS18B20 temperature sensor.

This sensor contains a nine-axis inertial measurement unit (IMU) that detects how far you’ve twisted, turned or tilted the handle, and uses that information to estimate the amount of water flow.
