Description

The YFS401 Water Flow Sensor (Sea, White) is a compact and efficient Hall effect flowmeter designed to measure flow rates from 0.3 to 6 liters per minute. Built with a plastic valve body and a magnetic rotor, it outputs a pulse signal proportional to flow rate, which can be easily read by microcontrollers such as Arduino or Raspberry Pi. With an operating range of 3.5–24V DC, waterproof design, and ±5% measurement accuracy, this sensor is ideal for coffee makers, irrigation systems, water dispensers, and DIY automation projects. Featured By RoboticsBD.
