Water Flow Sensor

Descriptions :

The YF-S201 is a water flow measurement sensor commonly used for measuring the flow rate of water in various applications. It is often employed in projects related to water flow monitoring, such as in irrigation systems, water dispensers, and industrial equipment. This sensor operates on the principle of a Hall effect sensor, where a magnetic field is used to detect the movement of a rotor, providing a pulse output proportional to the flow rate.

Here's a basic overview of the YF-S201 water flow sensor:

Key Features :

 1. Flow Rate Range : The YF-S201 is designed to measure flow rates within a range of 1 to 30 liters per minute (L/min). This range can vary based on the specific model or version of the sensor.

 2. Pulse Output : The sensor outputs a series of pulses where each pulse represents a certain volume of water passing through the sensor. The frequency of pulses is proportional to the flow rate.

 3. Hall Effect Sensor : The sensor utilizes a Hall effect sensor to detect the movement of a magnet within the sensor's rotor, generating electrical pulses.

 4. Voltage and Current Ratings : The sensor typically operates at a voltage of 5V and consumes a low amount of current, making it suitable for use with microcontrollers like Arduino.

 5. Connection Interface : The YF-S201 usually has three wires: VCC (power supply), GND (ground), and Signal (pulse output).

 6. Application Areas : Common applications include water flow monitoring in irrigation systems, industrial equipment, water dispensers, and more.

Flow Rate Calculation:

To convert the pulse count to a flow rate, you need to know the specifications of your specific YF-S201 sensor. The datasheet should provide details on the number of pulses per liter or gallon. Once you have this information, you can calculate the flow rate using the formula:

Flow Rate (L/min)=Pulses per Litre Pulse Count​×Time (minutes)
