It consists of a turbine-type rotor that is placed in the water stream, and as the water flows past the rotor, it causes the rotor to spin. The sensor measures the speed of the rotor and converts it to a flow rate. The sensor has a digital output, which means that it provides a digital signal that can be read by a microcontroller or other host device. The frequency of the pulses is proportional to the flow rate of the liquid passing through the sensor. That digital signal, whose frequency is in the range between 0Hz and 100Hz, can be read directly through one of the digital input/output pins of a microcontroller. ID 8.5mm / OD 11mm. The water flow sensor measures the rate of a liquid flowing through it. The YF-S402 water flow sensor consists of a plastic valve body, flow rotor, and hall effect sensor. It is usually used at the inlet end to detect the amount of flow. When liquid flows through the sensor, a magnetic rotor will rotate and the rate of rotation will vary with the rate of flow. The hall effect sensor will then output a pulse width signal. Connect it to a microcontroller and you can monitor multiple devices such as your coffee maker, sprinkler, or anything else, and control the water flow rate to suit your needs. Features: Compact and Lightweight: Easy to install and integrate into various systems. High Sealing Performance: Designed to prevent water leaks with a sealing ring. Stainless Steel Axis: Durable and abrasion-resistant. Digital Output: Provides a series of digital pulses proportional to the flow rate. Wide Voltage Range: Operates between 5V to 24V. RoHS Compliant: Meets environmental and safety standards. High Precision: Accurate measurement of water flow. Wide Flow Range: Measures flow rates from 0.3 to 6 liters per minute. Applications: Agriculture: Used in irrigation systems to monitor and control water usage. HVAC Systems: Helps in monitoring water flow in heating, ventilation, and air conditioning systems.
