contribution.Let's see how it works.
Reading Water Flow rate with Water Flow Sensor
This is part of a project I have been working on and I thought I would share it here since there have been
a few threads on how to read water flow rate in liters per hour using the Water Flow Sensor found in the
Seeed Studio Depo. It uses a simple rotating wheel that pulses a hall effect sensor. By reading these
pulses and implementing a little math, we can read the liquids flow rate accurate to within 3%. The
threads are simple G1/2 so finding barbed ends will not be that hard.
Hardware Installation
You will need Seeeduino / Arduino ,Water Flow Sensor,10K resistor,a breadboard and some jumper
wires.
Wiring up the Water Flow Sensor is pretty simple. There are 3 wires: Black, Red, and Yellow. Black to the
Seeeduino's ground pin Red to Seeeduino's 5v pin The yellow wire will need to be connected to a 10k
pull up resistor.and then to pin 2 on the Seeeduino.
Here is a fritzing diagram I made to show you how to wire it all
up.
