The YF-S201 Water Flow Measurement Sensor is an efficient solution for monitoring water flow in various applications. With a flow rate capacity ranging from 1 to 30 liters per minute, this sensor features a robust design, including a magnetic hall-effect sensor that accurately detects and outputs electrical pulses corresponding to water flow. The sensor's integrated hall-effect sensor is protected from water exposure, ensuring long-term durability and reliability. Each pulse generated by the sensor represents approximately 2.25 milliliters of water, making it easy to calculate the total flow by counting pulses.
This compact and easy-to-install sensor is ideal for basic flow measurement tasks and can be connected to standard 1/2" pipes. Note that the pulse rate may vary slightly depending on flow rate, fluid pressure, and sensor orientation, so careful calibration is required for precise measurements. Featured By RoboticsBD.
