The Gravity: Analog Water Pressure Sensor is a reliable and accurate liquid pressure sensing module designed for smart systems and IoT applications. Featuring the DFRobot Gravity 3-pin interface, it supports a 5V input and linear 0.5–4.5V analog output, making it easy to integrate with Arduino and other microcontrollers. With a measurement range of 0–1.6MPa and a precision of 0.5%FS, this sensor can be applied to household water systems, smart farming, environmental monitoring, and industrial automation. Its IP68 waterproof rating ensures stable performance in harsh conditions, while the G1/4 threaded port (with G1/2 to G1/4 adapter included) allows simple installation in water pipelines and tanks. Designed with durability in mind, it withstands up to 3.0MPa pressure and supports over 10 million cycles of use. Whether for detecting water flow, tank levels, or system pressure, this sensor provides fast, reliable, and long-lasting performance. Featured By RoboticsBD.
