The Gravity Analog Water Pressure Sensor is a simple yet powerful tool that helps you monitor water systems by detecting both the presence of water and measuring its pressure.
This DFRobot sensor uses a standard Gravity 3-pin interface that makes it compatible with Arduino and similar microcontrollers. It works with 5V input voltage and provides a linear output voltage between 0.5V and 4.5V that corresponds to the pressure level.
When used with a Gravity IO Expansion Shield, you can connect this sensor directly to your Arduino board without any complicated wiring, making it perfect for beginners and students working on water monitoring projects. This versatile liquid pressure monitor can be the foundation of many practical applications.
By combining it with components like solenoid valves and water turbine generators, you can build complete smart water systems for homes, gardens, or farms. The sensor works like a stethoscope for water pipes, helping you diagnose water flow issues and monitor pressure levels in real-time.
With its waterproof design, it can be used in various environments including indoor plumbing, outdoor water sources like rivers and lakes, and water storage tanks.
This makes it an excellent choice for smart home control systems, Internet of Things (IoT) projects, and equipment monitoring applications where water pressure data is important.
