Category: Water TDS, pH, Flow, Level and Pressure Sensor

This is a water pressure sensor that adopts a 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. 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, how strong the water pressure is. It can be widely applied to smart home control systems (SCS), the Internet of Things (IoT), and device detections.

Connection Diagram:


  1. Support water pressure detection of living environmental water systems, such as houses, gardens, and farms
  2. Support water pressure detection of the outdoor environment, such as rivers, lakes, and the sea
  3. Support water pressure detection of tanks
  4. Support liquid level detection in special situation detection in specified liquid
