The system has two 140 gallon fish tanks and three 4×8 grow beds filled with grow stones. The beds water flow control is metered with Arduinos with data from Adafruit flow sensors on each bed. The important part is the bed water control, that is controlled by Art Controllers. We have almost 100 fat Talipia fish to fertilize the plants. The room is red because of all the high power LED grow lights.
Measure liquid/water flow for your solar, computer cooling, or gardening project using this handy basic flow meter. This sensor sit in line with your water line, and uses a pinwheel sensor to measure how much liquid has moved through it. The pinwheel has a little magnet attached, and there’s a hall effect magnetic sensor on the other side of the plastic tube that can measure how many spins the pinwheel has made through the plastic wall. This method allows the sensor to stay safe and dry.
