Accurate
flow measurement is an essential step both in the terms of qualitative
and economic points of view. Flow meters have proven excellent devices
for measuring water flow, and now it is very easy to build a water
management system using the renowned water flow sensor YF-S201. For
example you can make a robotic cocktail dispensing machine, and can use
this sensors to accurately measure components like Soda, Water, etc.
YF-S201
1/2 inch Water Flow Sensor sits in line with the water line and
contains a pinwheel sensor to measure how much water has moved through
it. There is an integrated magnetic Hall-Effect sensor that outputs an
electrical pulse with every revolution. YF-S201 1/2 inch water flow
sensor has only three wires and it can be easily interfaced between any
microcontroller and Arduino board. It requires only +5V Vcc and gives
pulse output, the sensor needs to be tightly fitted between water
pipeline.
