Conclusion: Elevate Your IoT Projects void setup() Serial
: Set the generator frequency to match a specific flow rate. For example, to simulate 10 L/min, you would set the frequency to 75 Hz (since Implementation Tips Flow sensor YF-S201 - General Guidance - Arduino Forum or SD cards. Key Technical Specifications
The library allows you to adjust flow rates, enabling the simulation to generate the correct number of pulses per second, reflecting the real sensor's output of roughly 450 pulses per liter per minute. 2. Time and Cost Savings
: It is designed to work seamlessly with the Arduino Proteus Library , enabling a full virtual system with LCDs, relays, or SD cards. Key Technical Specifications
