## Description

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. Key Features Gravity 3-Pin Interface – Plug-and-play with Gravity-compatible boards Linear Analogue Output – 0.5–4.5 V proportional to 0–1.6 MPa IP68 Waterproof – Fully submersible sensor probe Wide Pressure Range – 0–1.6 MPa measurement, up to 2.0 MPa operating Fast Response – <2.0 ms response time Low Power – 2.8 mA quiescent current Specifications Medium – Non-corrosive liquid or gas Pressure Range – 0–1.6 MPa Normal Operating Pressure – ≤2.0 MPa Damage Pressure – ≥3.0 MPa Input Voltage – 5 V DC Output Voltage – 0.5–4.5 V (linear) Accuracy – 0.5–1% FS (0.5% at 0–55 °C) Quiescent Current – 2.8 mA Response Time – <2.0 ms Thread – G1/4 (G1/2 adapter included) Waterproof Rating – IP68 Operating Temperature – −20 °C to +85 °C Interface – Gravity 3-pin (Signal–VCC–GND) Service Life – 10,000,000 cycles Ideal For Household water pressure monitoring Garden and farm irrigation systems Tank and liquid level detection IoT smart water control systems Package Contents 1× Gravity Analog Water Pressure Sensor 1× G1/2 to G1/4 Thread Adapter Resources Wiki Documentation
