In this guide, we will be interfacing NPN Pulse Output Anemometer Sensor with Arduino and measuring the Wind Speed. An anemometer is a device used for measuring wind speed and direction. It is also a common Weather Station instrument.
In one of our previous projects, we measured Wind Speed using the Adafruit Anemometer sensor & also display the Wind Speed in Gauge on TFT LCD Display. But Adafruit Anemometer is an analog anemometer and requires a power of more than 7V for operation. Therefore we will be using a digital Anemometer in this project which has NPN Pulse Output. The NPN pulse output anemometer result is good & are also cost-effective & they operate at 5V only.
In this project, we will interface NPN Pulse Output Anemometer with Arduino & display the measured wind speed on a 16×2 LCD Display. This anemometer is capable of measuring wind speeds up to 70 m/s or 156 mph which should be adequate for our location.

I'm repliying to my own comment because I found a remedy.
Replace the command "init" on line 26 with the word "begin" and it works.

[@NiziYouTube]

Which option I have to select to get the same Anemometer:RS485 Speed,4-20mA Speed,0-5V Speed,0-10V Speed

[@infinitegaming2897]

Awesome tutorial keep share your thought with us thanks 👌👌👌

[@zishan.kaif17]

Great tutorial 👍

[@MrAlsan]

Awesome project 🤗👍

[@johnbrianalmazan6522]

what is the variable that holds the value of the wind speed? is the the "(Count * 8.75)/100"?

[@quentinducceschi6238]

If you want km/h you can multiply the m/s speed by 3.6

[@MrThisIsMeToo]

Thank you Captain Obvious.

[@gauravkunjwani4548]

Hiii, I have same type of anemometer, it's showing incorrect readings due to which it's showing trip signal, please guide how can I rectify this problem

[@OmarZ2000]

I have PR- 3000 - FSJT-V05
Shoudl I change something in connection or the code ?
Also, I follow the same steps that you did it
But there is an Error massege in [ lcd.init() ; ]

[@Counselor77]

Replace the command "init" on line 26 with the word "begin" and it works.

[@SC.243k]

Very good

[@user-ry8ew2ee6r]

why till 70m/s?

[@rehan_alammmblogs]

Awesome ❤️

Arduino: 1.8.19 (Windows Store 1.8.57.0) (Windows 10), Board: "Arduino Nano, ATmega328P"
\Arduino\sketch_may14a\sketch_may14a.ino: In function 'void setup()':
sketch_may14a:26:7: error: 'class LiquidCrystal_I2C' has no member named 'init'
lcd.init();
^~~~
exit status 1
'class LiquidCrystal_I2C' has no member named 'init'
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

[@markvalencia58]

Thanks it worked.

[@hobbychanel5798]

can you make a project esp wifi monitoring sistem for bylink-energy meter 12v power V/W/A

[@johnbrianalmazan6522]

My anemometer looks exactly like it, however its model name is ZTS-3000-FSJT-I20-60-1
Will this code work on mine?

[@kabitachand2222]

👍👍👍

[@gianpieroconflitti5838]

Do you sell this to me?

[@BarMagnet]

Using interrupts in such a way does not seem, to me, to be an efficient method of programming. Couldn't you just use a binary ripple counter (such as a 74hc4020) and save on the interrupts?

[@user-ry8ew2ee6r]

why using interrupt isn't efficient could you please elaborate??

[@BarMagnet]

​@@user-ry8ew2ee6rIt's just a thought. I avoid using function calls during the loop due to the overhead in clock cycles. Use a test flag to condition the function call. Same thing for interrupts. A counter chip can be used to minimize the calls.

[@BarMagnet]

​​​@@user-ry8ew2ee6rIt's just a thought. I prefer not to use function calls within the main loop because of the overheads. Interrupts are similar. In this case they could be replaced by a counter to minimize the calls.That interrupt could be engaged multiple times within the main loop.
