RB-See-356
SeeedStudio Water Flow Sensor (1/8")
Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water
flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor
outputs the corresponding pulse signal. This one is suitable to detect flow in water dispenser or coffee
machine.
