Gravity: Analog Water Pressure Sensor

Introduction

This is a water pressure sensor adopts 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.

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.
