Gravity: Analog Water Pressure Sensor
1101 units available with a short lead time.
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.
