In the world of embedded systems and IoT, the YFS201 Hall Effect Flow Sensor has become a staple for water heaters, coffee machines, and industrial metering. However, for years, there has been a glaring gap in the design workflow: simulation.
volatile int pulseCount = 0;
Output: It generates frequency pulses proportional to the flow rate. yfs201 proteus library exclusive

3. Industrial Conveyor Belt Speed
Attach the "OUT" pin to a counter module. The exclusive model allows you to rename "Flow Rate" to "Belt Speed (m/s)" in the schematic annotation—perfect for factory automation training. Pin Mapping in Proteus: | Virtual Pin |
Part 5: Why This Library is "Exclusive" – Troubleshooting Common Errors
Many users fail to get accurate results because they use generic signal generators. Here is why the exclusive model outperforms them:
