Water Flow Sensor Diagram

There will be no interrupt signal seen at the pin 2 of the arduino and the count of the flow frequency will be zero.
Water flow sensor diagram. In this project we will interface yfs201 hall effect water flow sensor with arduino for measuring flow rate and volume of water or any other liquid this is a very wonderful project that can be used in industry or at home or at water flow measurement application in water tap tunnel river etc. Water flow sensor consists of a plastic valve from which water can pass. Arduino water flow sensor working. If you want to measure the water flow in a network of water pipes or you can place just before a water tap to measure the water flow of single tap.
It is very simple to measure the water or liquid flow by using water flow sensor yf s201 with arduino this article describes about the water flow sensor and how the water flow sensor works then how to interface water flow sensor with arduino to take control on volume we need to measure water is essential to every thing here this article helps you to built water flow meter to measure the. Internally the output pin of the hall effect sensor is pulled high on the circuit board itself as you can see in the breakdown image show above. If the output valve of the pipe is closed the output of the water flow sensor is zero no pulses. Hence i have not used any external pull up resistors.
The sensor may be placed after the main gate valve of tank. The circuit diagram for arduino water flow sensor interface is shown in the image below. Water flow sensors are installed at the water source or pipes to measure the rate of flow of water and calculate the amount of water flowed through the pipe. Rate of flow of water is measured as liters per hour or cubic meters.
