Analog Water Pressure Sensor With Linear Voltage Output For Arduino And IoT Water Monitoring Systems
 

The Gravity Analog Water Pressure Sensor is a compact, easy-to-use pressure-sensing module designed for monitoring water pressure in pipelines, tanks, and fluid control systems. Featuring a standard Gravity 3-pin interface, the sensor operates from a 5V supply and provides a linear analog voltage output from 0.5V to 4.5V, enabling accurate pressure measurement through Arduino, ESP32, and other microcontroller platforms. Its plug-and-play design simplifies installation and reduces wiring complexity during development.

Designed for smart water management applications, the sensor can be combined with components such as solenoid valves, water flow sensors, and water turbine generators to create intelligent water control systems. By continuously monitoring water pressure, the sensor helps detect the presence of water, pressure fluctuations, and system performance. This makes it suitable for smart home automation, IoT monitoring networks, industrial equipment diagnostics, and water distribution systems.
