Water Flow Sensor YF-S401
This water flow sensor is a reliable and easy-to-install solution for monitoring water movement in small appliances like water dispensers, coffee machines, and other liquid-based systems. As water flows through the sensor, it spins an internal rotor which sends pulse signals that can be read by a microcontroller or monitoring system. It’s a great way to detect and respond to changes in water flow, whether you're building a DIY project or adding automation to your setup.
Designed with durability and performance in mind, this sensor features a compact body, smooth operation, and leak-proof construction. It’s ideal for hobbyists, makers, and engineers who need a practical and efficient way to measure water usage or trigger events when water starts flowing. Whether you’re working on a home automation project or a commercial prototype, this water flow sensor adds a smart and dependable layer of control.
