How to measure wind speed by using Anemometer with Arduino Uno || wind speed(m/s) || 100% work

3 роки тому

In this video, shows how to measure wind speed using wind speed anemometer and Arduino Uno. An anemometer is a device used for measuring wind speed and direction. It is also a common weather station instrument. There are many types of anemometer with medium and high costs such as cups, hot wire & windmill. The anemometer used here is the cup type. The anemometer wind speed range is 0 to 70m/s and minimum detectable wind speed: 0.2m/s. you can get a code from link below :

Hi, great video! Exactly what I was looking for. But I have a problem. I have a similar one to this anemometer. Only its model is different: PR-3000-FSJT-NPN. All other specifications are 1: 1 as the anemometer indicated in the video: 20 pulses per revolution, NPN output, 5V-30V DC, etc... I connected it according to the specified scheme and uploaded your sketch. Everything works, except for one thing: the values are doubled! I modified the sketch and realized that when the propeller is fully turned, the Arduino counts 40 instead of 20 pulses! I also tried to put a 5.1KOhm resistor between the ground and the NPN output (as some recommend), but then it didn't even return values. Of course, I can leave it as it is, and just modify the sketch so that one revolution is 40 pulses, but I would like to understand why this happens, and if possible to fix it! Can you help me?! Thanks!

you may check the code inside, there have a formula for 20 pulse, for your case, just change the 20 pulse value to 40 will do. Thanks

@yochaig1957 2 роки тому

The third argument to "attachInterrupt" cannot be CHANGE anyway, because it will raise 40 pulses per rotation, instead of 20, as specified by the anemometer's spec.

Hi, thanks for your video. I have a sensor quite similar but unfortunately working on RS485 (precisely model PR-3000-FSJT-N01), working between 10-30V DC. I can power it externally obviously but is it possible to read winds data with this different model? Thank you!

@mybotic_tech Рік тому

Rs485 use different communication method, it is different from this sensor...

You can use RS485 to IP - LAN (Ethernet) converter

wooow, this is fantastic, it worked perfect for my sensor But I have a question, in my datasheet it is said that I need a resistor like 5.1K , but it works fine without it and also only with 3 wires.

@mybotic_tech 2 роки тому

In the code ady set pull up, so no need resistor to make pull up.

Baga de seama ca "The third argument to "attachInterrupt" cannot be CHANGE anyway, because it will raise 40 pulses per rotation, instead of 20, as specified by the anemometer's spec.". In plus "The Rotations reset statement (Rotations = 0; //Set Rotations count to 0 ready for calculations) should be BEFORE enabling again the interrupts (sei(); //Enables interrupts).".

Hi. I bought NPN anemometer from your shopee, currently Im testing to do IoT Anemometer. Is it possible to connect nodemcu esp8266 with anemometer, cause I got 0m/s output speed when use nodemcu. I tried with arduino uno, I get the exact value. Thanks.

@mybotic_tech Рік тому

mybotic.com.my/durian-uno-enhancement-of-arduino-uno-for-iot-project-education?search=Durian%20uno You need to use this, durian uno Nodemcu operating voltage 3.3v, anemometer at least 5v signal, so your nodemcu won't work

I have PR-3000-FSJT-N05V Is this steps will work with it or I should change something ?

Can, depend on your code

Does it work with arduino leonardo?

@mybotic_tech Рік тому

Yes, working, the things you need to know is the interrupt pin may different from uno, you need to change the signal pin to correct interrupt pin in leonardo
