This is YF-S201 Water Flow Measurement Sensor with 1-30Leter/min Flow
Rate in white color. This sensor sits in line with your water line and
contains a pinwheel sensor to measure how much liquid has moved through
it. There’s an integrated magnetic hall effect sensor that outputs an
electrical pulse with every revolution. The hall effect sensor is sealed
from the water pipe and allows the sensor to stay safe and dry.
By counting the pulses from the output of the sensor, you can
easily calculate water flow. Each pulse is approximately 2.25
Note this isn’t a
precision sensor, and the pulse rate does vary a bit depending on the
flow rate, fluid pressure, and sensor orientation. It will need careful
calibration if better than 10% precision is required. However, it’s
great for basic measurement tasks!
We have an example Arduino sketch(check the ATTACHMENTS tab) that can
be used to quickly test the sensor, it will calculate the approximate
flow of water in liters/hour. The pulse signal is a simple square wave
so it’s quite easy to log and convert into liters per minute using the
Red wire: +5V
