YF-201C Water Flow Sensor - G1/2" Coupling

With this sensor you can easily measure the flow of liquids (water).

The sensor has a standard 1/2" coupling (21mm) on both sides and is therefore easy to connect to, for example, a Gardena garden system (see images)(Gardena coupling not included).

Pinout:

• Red: Vcc/plus (5-15V)
• Black: GND/min
• Yellow: Signal

Modify the following part of code around line 17:

float calibrationFactor = 4.5;

To:

float calibrationFactor = 5.5;

Note: We cannot provide any warranty when this product is used with any liquid other than clean spring/tap water (non-potable).

Note: The liquid can only flow in one direction, this is indicated by an arrow.
