More info


Gravity: Digital Water Flow Sensor is a sensor that measures the liquid flowing through it. It is made of a plastic body, a flow impeller and a Hall sensor. The flowing liquid causes the rotor to rotate. The higher the liquid flow, the higher the rotational speed. Hall sensor detects each rotation and sends a signal in the form of a pulse. Each revolution equals about 1/5880 liters of liquid. The sensor can be used in such projects as a coffee machine or sprinkler. The module is supplied with a voltage of 5 ... 12 V and can measure the liquid flow in the range of 0.3 ... 6 L / min.


  • Permissible liquid pressure: less than 0.8 MPa
  • Measured flow range: 0.3 ... 6 L / min
  • Accuracy: ± 5%
  • High state of the output pulse:> 4.5 VDC (with 5 V supply)
  • Low output pulse state: <0.5 VDC (at 5 V supply)
  • Fluid flow calculator: 1L = 5880 pulses
  • Operating humidity range: 35% ~ 90% RH (without frost)
  • Inner diameter: 4 mm
  • Outer diameter: 7 mm
  • Power consumption: 15 mA (with 5 V power supply)
  • Supply voltage: 5 ... 12 V
  • Dimensions: 58 x 35 x 26 mm
  • Weight: 30 g
