About this product
FS-300A Hall-effect water flow sensor with a G3/4 threaded connection, measuring flow from 1 to 60 liters per minute. It outputs a pulse signal whose frequency tracks the flow rate, which is commonly counted on a microcontroller interrupt pin for water dispensing, irrigation, and cooling projects.

Frequently asked questions
What is the price of FS-300A Water Flow Sensor G3/4 Thread 1-60 L/min in Egypt?
FS-300A Water Flow Sensor G3/4 Thread 1-60 L/min currently costs between 375 and 500 EGP across 2 offers in Egypt.
Where can I buy FS-300A Water Flow Sensor G3/4 Thread 1-60 L/min in Egypt?
FS-300A Water Flow Sensor G3/4 Thread 1-60 L/min is available from RAM Electronics and Circuits Electronics. Compare the offers above to find the best price.
How do I wire the FS-300A flow sensor?
Typically the red wire is VCC, the black wire is GND, and the yellow wire is the pulse output. Confirm the colors on your unit. Connect the pulse wire to an interrupt-capable pin and count pulses over time to calculate flow.
Can I power it from a 3.3 V board?
No. The supply range starts at 3.5 V, so power the sensor from 5 V or higher. If the pulse line can exceed the logic level of a 3.3 V microcontroller, use a voltage divider or level shifter on the signal wire.
