Generic YF-S402C Water Flow Sensor Flowmeter G3/8 0.3-10L/min 5-18V
The YF-S402C is a hall-effect-based water flow sensor with a G3/8 thread, designed for 5-18V DC systems and compatible with Arduino, Raspberry Pi, and other microcontrollers for monitoring liquid flow rates from 0.3 to 10 liters per minute.
Features
- Hall-effect sensor with magnetic rotor for pulse-width output proportional to flow rate.
- G3/8 threaded plastic valve body for easy inline installation in water lines.
- Wide operating voltage range from 5V to 18V DC for flexible system integration.
- Flow measurement range from 0.3 L/min to 10 L/min with ±5% accuracy.
- Durable construction rated for water pressure up to 0.8 MPa and temperatures from 0°C to 80°C.

The YF-S402C water flow sensor operates on a hall-effect principle, where a magnetic rotor spins as liquid passes through the valve body. The embedded hall sensor detects each rotation, generating a digital pulse signal whose frequency is directly proportional to the volumetric flow rate. This output can be easily read by a microcontroller’s interrupt or counter pin for precise flow monitoring and control.
Constructed with a robust plastic housing and standard G3/8 threads, the sensor is designed for direct inline installation in water systems. It is rated for a maximum working pressure of 0.8 MPa and can operate in environments with 5% to 90% relative humidity, making it suitable for a variety of residential and light industrial liquid monitoring applications.
