β‚Ή1,859.00Price
πŸ’§ DFRobot Gravity Analog Water Pressure Sensor
🧩 Overview
  • Analog water pressure measurement sensor
  • Part of DFRobot Gravity series (plug-and-play)
  • Designed for liquid pressure detection in pipes, tanks, and systems
  • Compatible with Arduino, ESP32, Raspberry Pi
βš™οΈ Working Principle
  • Uses piezoresistive pressure sensing element
  • Water pressure applies force on internal diaphragm
  • Causes change in electrical resistance
  • Internal circuit converts it into analog voltage output (linear)
πŸ‘‰ Works like a pressure-to-voltage converter
