![]() ![]() To measure the pulses, we are going to use Arduino UNO. Now, all we have to do is to measure the time for the pluses or to count the number of pulses in 1 second and then calculate the flow rates in liter per hour (L/Hr) and then use simple conversion formula to find the volume of the water which had passed through it. Due to this, whenever water flows through the valve it generates pulses. The shaft of the turbine wheel is connected to a hall effect sensor. To connect with the pipe and water flow sensor, I used two connectors with a female thread as shown below.Īccording to YFS201 Specifications, the maximum current it draws at 5V is 15mA, and the working flow rate is 1 to 30 liters/minute. When the liquid flows through the sensor, it makes contact with the fins of the turbine wheel, which is placed in the path of the flowing liquid. The picture of the YFS201 sensor module alone is shown below. Its design is in such a way that the hall effect sensor is sealed off from the water, and allows the sensor to stay safe and dry. The water flow sensor is integrated with a magnetic hall effect sensor, which generates an electric pulse with every revolution. Hall effect is the production of the potential difference across an electric conductor when a magnetic field is applied in the direction perpendicular to that of the flow of current. The water flow sensor works on the principle of hall effect. The working of the YFS201 water flow sensor is simple to understand. The water flow sensor consists of a pinwheel sensor that measures the quantity of liquid that has passed through it. The yellow wire is used for output(pulses), which can be read by an MCU. The red wire is used for supply voltage which ranges from 5V to 18V and the black wire is connected to GND. ![]() YF-S201 sensor operates below +80☌ temperature.Ħ.The sensor has 3 wires RED, YELLOW, and BLACK as shown in the figure below.
