The flow meter allows a hard limit to be set for the maximum amount of water allowed into the tank. He’s used an Arduino Micro to tie the project together, which also handles a real-time clock ...

As soon as the moisture level reaches upwards of 70%, the Arduino stops the water pump. This controlled water flow ensures the plant never gets too much or too little.

Using a YF-S201 flowmeter on a Raspberry Pi, the code uses Python to populate a database. The meter will need to be calibrated to get an exact volume measurement. There are many ways to measure flow.

Mechanical water meters also do not work well when the water flow is low. Vortex Flow Meters Vortex water flow meters use vortices shed from a sensor immersed in the flow. Vortices are forces of ...
