{"title":"Gravity: Analog Water Pressure Sensor","handle":"gravity-analog-water-pressure-sensor","url":"/products/gravity-analog-water-pressure-sensor","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.\n\nThe 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.\n\nKey Features\n\n\nGravity 3-Pin Interface – Plug-and-play with Gravity-compatible boards\n\nLinear Analogue Output – 0.5–4.5 V proportional to 0–1.6 MPa\n\nIP68 Waterproof – Fully submersible sensor probe\n\nWide Pressure Range – 0–1.6 MPa measurement, up to 2.0 MPa operating\n\nFast Response – <2.0 ms response time\n\nLow Power – 2.8 mA quiescent current\n\n\nSpecifications\n\n\nMedium – Non-corrosive liquid or gas\n\nPressure Range – 0–1.6 MPa\n\nNormal Operating Pressure – ≤2.0 MPa\n\nDamage Pressure – ≥3.0 MPa\n\nInput Voltage – 5 V DC\n\nOutput Voltage – 0.5–4.5 V (linear)\n\nAccuracy – 0.5–1% FS (0.5% at 0–55 °C)\n\nQuiescent Current – 2.8 mA\n\nResponse Time – <2.0 ms\n\nThread – G1/4 (G1/2 adapter included)\n\nWaterproof Rating – IP68\n\nOperating Temperature – −20 °C to +85 °C\n\nInterface – Gravity 3-pin (Signal–VCC–GND)\n\nService Life – 10,000,000 cycles\n\n\nIdeal For\n\nHousehold water pressure monitoring\nGarden and farm irrigation systems\nTank and liquid level detection\nIoT smart water control systems\n\n\nPackage Contents\n\n1× Gravity Analog Water Pressure Sensor\n1× G1/2 to G1/4 Thread Adapter\n\n\nResources\n\nWiki Documentation\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":8291,"title":"Default Title","sku":"DF-SEN0257","price":30.49,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":1357,"option1":"Default Title"}]}
