Gravity: Analog Water Pressure Sensor (non-immersible)

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. You may also check Liquid Sensor Selection Guide to get better familiar with our liquid sensor series.

Briefly speaking, this water pressure sensor is a stethoscope to a water pipe. It will help you to diagnose whether there is water, and how strong the water pressure is. It can be widely applied to smart home control systems (SCS), Internet of Things (IoT), and device detections.
