We will then integrate the hardware with iot server.
Hall effect sensor flow meter.
Gikfun water flow sensor 1 30l min for arduino ek1457.
Hall effect sensors are used for proximity sensing positioning speed detection and current sensing applications.
The hall effect sensor outputs the corresponding pulse signal.
We will interface yfs201 hall effect water flow sensor with nodemcu esp8266 board.
Frequently a hall sensor is combined with threshold detection so that it acts as and is called a switch.
Hall effect flow sensor provides low cost solution for water flow measurement.
Make sure to select one that will cover your needs.
Digiten g1 water flow hall effect sensor switch flow meter flowmeter counter 1 60l min.
The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.

There s an integrated magnetic hall effect sensor that outputs an electrical pulse with every revolution.
This type of sensor can be found on different diameters water pressure mpa and flow rate l m ranges.
We will display the water flow rate total volume in 0 96 oled display.
By counting the pulses from the output of the sensor you can easily calculate the water flow rate.
Each pulse is approximately 2 25 milliliters.
This sensor sits in line with your water line and contains a pinwheel sensor to measure how much liquid has moved through it.
The water flow sensor is integrated with a magnetic hall effect sensor which generates an electric pulse with every revolution.
