is a turbine-based water flow sensor. As water flows through the rotor, it spins a turbine. A magnetic Hall Effect sensor inside the unit counts the rotations, sending a digital pulse signal for every revolution. 5V – 18V DC Flow Range: 1 – 30L/min Output Signal: Pulse (NPN output) Cable Color Code: Red (5V), Black (GND), Yellow (Signal) 2.

If you need a more realistic simulation—for example, one that automatically responds to a control signal—you can using Proteus’s modelling tools. This is more involved, but it yields a reusable library part that can be saved, shared, and used in multiple projects. yfs201 proteus library
If a dedicated library is unavailable, you can simulate the sensor's behavior using standard Proteus components: Clock Generator Pulse Generator
Connect the VCC pin of the sensor model to a +5V Generator object. Connect the GND pin to the Ground terminal object.
Open Proteus ISIS and create a new project. Gather and wire the components according to the structural breakdown below. Component List Warning: Many websites host fake or virus-laden “Proteus

Proteus does not include a visual simulation model for the YF-S201 sensor out of the box. A custom library solves this by providing a graphical component for your schematic capture screen and an underlying SPICE or VSM simulation model. Primary Engineering Benefits A magnetic Hall Effect sensor inside the unit
The sensor typically has three pins that you must connect to your microcontroller (e.g., Arduino): : Connect to +5V. GND : Connect to the common Ground.
