Water flow sensor G1/2" ZJ-S201 Hall effect, plastic DN15, 1–30 l/min, 5–24 V DC – Seeed Studio 314150005

Key features

• Plastic valve body with internal rotor and Hall-effect sensor: the water spins the rotor, whose speed changes with the flow rate, and the sensor outputs the corresponding pulse signal
• G1/2" (DN15) double male connections
• Compact and easy to install
• High sealing performance, water pressure up to 1.75 MPa
• RoHS compliant
