The model then toggles the output pin at the calculated rate. For example, if you connect a potentiometer to the input pin and set it to 2.5V, the model outputs a 37.5 Hz signal (since ( 2.5V/5V \times MaxFlow(30L/min) = 15L/min ), and ( 15 \times 7.5 = 112.5Hz)? Wait—correction: The mapping must follow the real formula: ( F = 7.5 \times Q ). So, the library internally maps voltage to Q, then Q to F.
Technically, you can. A pulse generator will produce a square wave. But a pulse generator is . It does not change its frequency based on a variable (e.g., a potentiometer knob or a sensor input). In a real YF-S201, the frequency changes instantly as water flow changes. Without a dynamic simulation model, you cannot test code that calculates flow rate in real-time. yf-s201 proteus library
The is a simulation model that allows engineers and students to test water flow measurement circuits before physical prototyping . Since Proteus does not include this specific sensor in its default database, a third-party library is required to simulate its Hall effect-based pulse generation.
