The Gravity Analog Water Pressure Sensor measures water or gas pressure and outputs a linear 0.5–4.5 V analogue signal proportional to the applied pressure (0–1.6 MPa). Using the DFRobot Gravity 3-pin interface, it connects directly to Arduino and other 5 V microcontrollers for easy integration into water monitoring and control systems.
The sensor features a G1/4 thread fitting (with a G1/2 to G1/4 adapter included), IP68 waterproof rating, and compatibility with non-corrosive liquids and gases. Suitable for household water systems, garden irrigation, tank level monitoring, and environmental water pressure detection.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- Thread
- A low-power wireless mesh networking standard designed for smart home and IoT devices. It matters because Thread devices can relay messages through each other, helping build reliable networks for sensors and controllers.
