The exclusive library uses a "Pull-up" configuration. Add a 10k resistor from OUT to VCC in your schematic. The model expects an open-collector output.
// YFS201 Flow Sensor with Interrupts const int flowSensorPin = 2; // Use interrupt pin 2 (INT0) on Arduino UNO volatile unsigned long pulseCount = 0; float flowRate = 0.0; unsigned long totalPulses = 0; unsigned long previousMillis = 0; const unsigned long interval = 1000; // Calculate every 1 second

: Use the 2D Graphics Box Tool to draw a rectangle representing the sensor. Add Pins : Place three pins using Pin Mode . Pin 1 (Red) : VCC (Power) Pin 2 (Black) : GND (Ground) Pin 3 (Yellow) : Pulse Output (Signal)
The YF-S201 relies on a magnetic pinwheel and a Hall effect sensor. When liquid passes through the casing, it drives the rotor. The internal Hall effect sensor outputs high and low digital pulses proportional to the rotor's speed. Key Hardware Specifications 5V to 18V DC Output Type: 5V TTL digital pulse train Flow Rate Range: 1 to 30 Liters per minute (L/min) Fluid Pressure Limit: ≤is less than or equal to Flow Pulse Characteristic: is the frequency in Hz, and is the flow rate in L/min) Why You Need a Proteus Simulation Model The exclusive library uses a "Pull-up" configuration
In the world of embedded systems and IoT, the 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.
This comprehensive guide introduces an exclusive Proteus simulation model for the YF-S201 sensor. It covers everything from installation to writing firmware for precise flow measurement. Understanding the YF-S201 Water Flow Sensor // YFS201 Flow Sensor with Interrupts const int
Wire the pin of the YF-S201 sensor to Digital Pin 2 of the Arduino Uno. Pin 2 is highly recommended because it supports hardware interrupts ( INT0 ).
The package should contain two critical files:
void setup() Serial.begin(9600); pinMode(flowSensorPin, INPUT_PULLUP); attachInterrupt(digitalPinToInterrupt(flowSensorPin), pulseCounter, RISING);
