: Connect to a digital pin on your microcontroller (e.g., Arduino Uno pin 2 or 3 for interrupts).

As water passes through the casing, it forces an internal rotor to spin. A Hall effect sensor detects this rotation and generates a pulse train. The frequency of this output pulse changes in direct proportion to the velocity of the liquid flow.

The YF-S201 is a Hall-effect-based water flow sensor. It consists of a plastic valve body, a rotor (impeller), and a Hall-effect sensor. When water flows through the sensor, the rotor spins. A magnet attached to the rotor activates the Hall-effect sensor, which generates a square wave pulse. The frequency of this pulse is directly proportional to the flow rate.

There may be times when a dedicated library is not available, or you need to test your system's response to very specific, non-standard flow patterns. In these cases, a common practice among experienced Proteus users is to simulate the sensor using a . This method works because the sensor's signal is a simple square wave, and you can use the equation Flow Rate (Q) = Pulse Frequency (F) / 7.5 to control the simulation. yf-s201 proteus library

: Uses a "Test Pin" (often connected to a potentiometer) to manually adjust and simulate different water flow rates during live simulation. Standard Interface

Click on the LOGICSTATE component to toggle it between High and Low (1 and 0). Every toggle counts as a pulse for your Arduino.

Advanced users can create a Proteus model using the (C++ or Visual Basic). This is overkill for most hobbyists, but it’s an option in professional settings. : Connect to a digital pin on your microcontroller (e

Optional: Connect a 10kΩ pull-up resistor between the signal pin and +5V.

The sensor model requires an initial flow rate parameter. Fix: Double-click the YF-S201. Look for a property like FLOW_RATE . Set it to a positive integer (e.g., 10). If the property doesn’t exist, the library is a passive model – replace it with a pulse generator as a workaround. The frequency of this output pulse changes in

Navigate to the Proteus installation directory. Typically:

volatile int pulseCount = 0; float flowRate = 0.0; float totalLiters = 0.0; unsigned long lastTime = 0;
