Hi,

Found this sensor, price is Euro 36. Could this be a replecement for the FO windspeed meter?



The wind speed sensor is composed of a shell, three wind cups and a circuit module, which is made of aluminum alloy material. The whole sensor has a high strength, weather resistance, corrosion resistance and water resistance, will be to ensure the long-term use of the instrument, and the accuracy of the wind speed collection.It is very suitable for outside measurement.

Specifications:
Material : Aluminium alloy
Color：Black
NOTE:please choose the type you want and leave us a message,or we will send at random.


Accuracy: + 1m/s
Start wind: 0.2-0.4m/s
Voltage output:
Range: 0-32.4m/s
Supply voltage: DC 7V~24V
Output signal: 0.4~2V
Wind speed = (Output voltage -0.4) /1.6*32.4

Current output type:
Range: 0~32.4m/s
Supply voltage: DC 12V-24V
Output signal: 4~20mA
Load capacity: ≤ 200Ω
Wind speed = (output current -4) /16*32.4

Pulse output type：
Range: 0~60m/s
Output signal: pulse (each pulse corresponds to 0.88m/s)
Supply voltage: DC 5V~24V

485 type：
Range: 0~32.4m/s
Supply voltage: DC 7V~24V
Communication protocol: Modbus-RTU

Features：
- Small size, aluminum alloy material, high strength.
- Exquisite appearance, high precision measurement
- Long signal transmission distance, strong anti-interference ability
- Low power consumption, Wide range, good data information
- Easy to installation , easy to carry

Hi,

If you choose the pulse version, and power it with just 5V, theoretically it should work with the WeatherDuino Pro2.

However it will not be a direct replacement for the FO anemometer, as it will require some changes on the TX software. If you decide to go for this anemometer, I will work with you to add support for it on the software. It will be a simple task.

You should inquire the supplier about how many pulses are produced by each revolution, most do 1 pulse per revolution, but the FO per example, produces two. Know this info is very important.

Congratulations by your weather page, looks great, and thanks for the reference to the WeatherDuino Pro2.

Hi,

Yes that looks to be a nice anemometer at a reasonable price (for the apparent quality).

Note that there is a minor "error" in their pulse specification. What they probably mean is "Output signal: pulse (each pulse per second corresponds to 0.88m/s)" or simply "each pulse represents 0.88 metres of Wind Run".

I believe the (claimed) corresponding figure for the Fine Offset is 1.5 mph (per pps) or 0.67 metres/sec, so you may need to increase the scale factor by about 1.31 (or +31%).

Cheers, Alan.

Hi,

Some time ago, during more or less a month, I have installed side by side an FO and a Inspeed Vortex Digital 8. Supposing the Inspeed is more reliable (and it is) than the FO, I found that to get similar readings for the average wind speed with the FO, a had to slightly change the claimed values from 1.5 mph (per pps) or 0.67 metres/sec, to 1.4 mph (per pps) or 0.63 metres/sec. For FO anemometers the WeatherDuino Pro2 software is using the last values.

Ok, thank you. When i need help i'll ask!

Hi,

Thankx, that's what they mean Thinking about to order one. They also have wind direction meter.

Hi,

I have one of these anemometers here it is a pulse type and if I could use with Weatherduino would be good.
The unit is very well made and looks like it would long lasting.
The price is attractive also.

Hi,
A link to the supplier ?
Thanks

The WeatherDuino Pro2 will work with virtually any pulse based anemometer, whose pulse is no more than 5V, and since we know some data about it.

I don't have one of these units to test, if you want to test it, give me by PM an e_mail address and I will send you a modified TX software that should work with it.
If possible, please try to determine how many pulses per revolution it produces, you can do it with a multimeter.
Thanks

Hello Group,I now have my Chinese anemometer on test with Weatherduino and it is working very well.
I will leave on test and give another report next weekend.
Cheers,Denis

Hola es posible utilizar este aparato con weatherduino.
Gracias
