1/2 inch Water Flow Sensor - YF-S201 with 1-30Liter/min Flow Rate
This sensor is a YF-S201 Water Flow Measurement Sensor with a white color and a flow rate of 1-30 liters per minute. It measures the amount of liquid passing through your water line by using a pinwheel sensor. The sensor has a magnetic hall effect sensor that produces an electric pulse every time the pinwheel rotates. The hall effect sensor is isolated from the water pipe, so it stays dry and safe.
You can calculate the water flow by counting the pulses from the sensor output. Each pulse corresponds to about 2.25 milliliters of liquid.
This sensor is not very accurate, and the pulse rate may change depending on the flow rate, fluid pressure, and sensor position. You will need to calibrate it carefully if you want more than 10% precision. But it is good 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 following formula.
