Gravity Analogue Water Pressure Sensor, 0-1.6MPa, G1/4 Thread

The Gravity Analogue Water Pressure Sensor from DFRobot is a precision instrument designed for monitoring and measuring water pressure in a wide variety of applications. This sensor provides a simple, plug-and-play solution for integrating pressure sensing into electronic projects, thanks to its standard Gravity 3-pin interface that connects directly to compatible controller boards.

This sensor is your reliable diagnostic tool for any water system, acting like a stethoscope for a water pipe. It enables users to accurately determine the presence of water and measure the exact pressure within the line. It operates on a standard 5V DC input, providing a linear voltage output between 0.5V and 4.5V that corresponds directly to the measured pressure, making it exceptionally easy to read with microcontrollers like Arduino.

Key Applications & Features

The sensor is built for versatility. It features a robust G1/4 threaded port for easy installation into plumbing systems and includes a G1/2 to G1/4 adapter. With an IP68 waterproof rating, it is fully protected against dust and long-term immersion, making it suitable for demanding environments. Its high accuracy, fast response time, and long service life ensure reliable, long-term performance.

Whether you are building an automated irrigation system for a garden, monitoring water levels in a tank, or collecting environmental data from a river, this sensor provides the critical data needed for smart control and decision-making. It is an essential component for hobbyists, educators, and engineers developing smart home systems, Internet of Things (IoT) devices, and industrial monitoring solutions.
