## Description

This 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. Use with a [DFRobot Gravity IO Expansion Shield](https://core-electronics.com.au/io-expansion-shield-for-arduino-v7.html), the water pressure sensor can be plugged into an Arduino board, wiring-free. Put it with [Solenoid Valve](https://core-electronics.com.au/12v-solenoid-valve-1-2.html), [Water Turbine Generator](https://core-electronics.com.au/water-turbine-generator-5vdc.html) and other sensors, you can build a smart water control system.

As we sometimes get asked - we have no info suggesting this will work in air-only setups. The manufacturer indicates water/liquid use.

Briefly speaking, this water pressure sensor is a stethoscope for a water pipe. It will help you to diagnose whether there is water, and how strong the water pressure is.

### Applications

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