G1/2 Water Flow Sensor – Hall Effect, 1–30L/min Range, Accurate Water Flow Measurement

Struggling to monitor water flow accurately in your DIY or industrial setup? The G1/2 Water Flow Sensor from amiciKart uses proven Hall Effect technology to deliver precise, real-time flow readings — making it the go-to choice for makers, engineers, and hobbyists across India.

This sensor measures water flow in the range of 1–30 litres per minute and outputs a clean pulse signal that any microcontroller can read. With a standard G1/2 (½ inch) external thread, it fits seamlessly into most water lines, pipes, and dispensers without any special adapters. The wide operating voltage of DC 3.5V to 24V makes it natively compatible with Arduino, ESP32, Raspberry Pi, and 12V industrial control systems — no level shifters needed in most cases. Built to handle water pressure up to 1.75 MPa and temperatures from -25°C to +80°C, this sensor performs reliably whether you are building a smart irrigation controller, a water purifier, a coffee machine, or an industrial fluid monitoring system.

The Hall Effect mechanism ensures non-contact sensing — the magnetic rotor inside spins with water flow and generates pulses without any electrical contact with the liquid, giving you long service life and consistent accuracy. Maximum current draw is just 15 mA at 5V, keeping your power budget lean. Whether you are a student prototyping a water meter, a startup building IoT devices, or a technician maintaining dispensing equipment, this sensor delivers dependable performance at an unbeatable price point.
