This water pressure sensor adopts the 3-pin DFRobot Gravity interface. It supports a standard 5V input and a linear voltage output of 0.5~4.5V. It is compatible with multiple Arduino controllers. In conjunction with the DFRobot Gravity IO Expansion Shield, the water pressure sensor can be connected to an Arduino board without wiring. When combined with an electrovalve, water turbine generator, and other sensors, you can create a smart water control system. This water pressure sensor acts as a stethoscope for water pipes, helping you diagnose whether there is water and how strong the water pressure is. It can be widely applied in smart home control systems (SCS), the Internet of Things (IoT), and device detection.

• Support for water pressure detection in water supply systems, such as homes, gardens, and farms.
• Support for water pressure detection in outdoor environments, such as rivers, lakes, and seas.
• Support for water pressure detection in tanks.
• Support for liquid level detection in special conditions.
