AJMRTC YFS401 Hall Effect Water Flow Sensor, 6mm Hose Connection Liquid Flow Meter for Coffee Machine Water Purifier, Pulse Output Flow Monitoring Sensor for LiquidControl DIY Projects

AJMRTC YFS401 water flow meter adopts hallsensing principle to detect liquid flow velocity. It comes with 6mm hose barb ports for direct connection with corresponding soft hoses. When water flows through the sensor, the internal impeller rotates, and the hall unit outputs pulse signals proportional to flow rate. Singlechip microcontrollers can receive these pulses to calculate realtime water flow and cumulative water volume. Operating at DC 5V, this sensor features low power draw and compact size. It is commonly used for coffeemachine flow feedback, waterpurifier flow monitoring and other smallliquidcircuit equipment modification. Please install horizontally and avoid debris entering the sensor cavity to prevent impeller jamming.
