Gravity: Analog Water Pressure Sensor Brand_Great Scott Gadgets A micro usb cable isThis is a water pressure sensor that adopts the DFRobot Gravity 3 pin interface. It supports standard 5V voltage input and 0. 5~4. 5V linear voltage output. It is compatible with multiple Arduino controllers. Coordinate with a DFRobot Gravity IO Expansion Shield, the water pressure sensor can be plugged into an Arduino board, wiring free. Put it with Solenoid Valve, Water Turbine Generator and other sensors, you can build a smart water control system.
