About this item

The DFRobot Gravity: Analog Water Pressure Sensor is a robust, accurate, and easy-to-use sensor designed to measure the water pressure of non-corrosive liquids in a variety of environments. Built with industrial-grade components, this sensor is based on a high-quality piezoresistive pressure transducer, delivering stable and precise analog output proportional to the measured pressure. With a measurement range typically from 0 to 1.6 MPa, it is ideal for applications such as smart water systems, pipeline pressure monitoring, home automation, and environmental sensing. The sensor outputs a linear voltage signal (0.5V–4.5V) that can be easily read using an analog input pin on an Arduino or other microcontroller platforms. Encased in stainless steel and waterproof housing (IP68 rated), the sensor is highly durable and suitable for continuous submersion or harsh outdoor conditions. It uses a standard G1/4” threaded interface, allowing easy installation into common water pipe systems. This sensor is part of the DFRobot Gravity series, meaning it features a 3-pin Gravity interface for simple, plug-and-play connectivity with DFRobot development boards, greatly reducing wiring complexity and accelerating prototyping.
