Hello, I would like to know if I can use this product in real projects, if it is patented or has a license
JaneYu slightly confused with the solution. i've done exactly as the wiki says and copied the code in word for word however the results I get every half a second fluctuate between 4.something and 8.something. Its never constantly the same....it just goes between these 2 values, even if I stop the cups from moving.
JaneYu Hi all, actually I've figured it out myself. I'm using a nano rp2040 and A0 appears to be used for something. I've swapped it to A1 and its now working really well. I was unsure on if it was reading mph or m/s so I bought an anemometer from amazon to check the readings, the code on the wiki with the nano rp2040 with a perm 9v power supply is providing accurate mph output.
Hi Nacho,
The resistance value is the value between 0 and 1023. coming in from your potentiometer:
int sensorValue = analogRead(A0);
To change the values from 0-1023 to a range that corresponds to the voltage the pin is reading, you'll need to create another variable, a float, and do a little math. To scale the numbers between 0.0 and 5.0 (since 5V is in the acceptable range), divide 5.0 by 1023.0 and multiply that by sensorValue :
float voltage= sensorValue * (5.0 / 1023.0);
JaneYu Hi, we haven't provide some demo about current, you could find some module about how to test current.
JaneYu Hi Maria,
I assume the problem you are referring to is the same constant voltage value. Could you kindle provide us a picture of your connection setup. As well as if you were able to get it working correctly in a controlled environment by following our wiki. Thanks.
JaneYu Hi,
The voltage between yellow and black is volatge signal. 0.8v looks like a correct value.
JaneYu the problem is that 0.8V is constant. The Pinwheel stands or moves at a high speed, still we get 0.8V What can we do?
0.8V measured between yellow and black. 24V measured between red and black
JaneYu We haven't tested it in such high wind speed situation, so can't give a certain answer to your question. I think if you are worried about wind damage the sensor, you may want to keep it inside while towing or give it a protection cover.
JaneYu Thank you for your reply. I have placed an order. In a few months I will test at highway speeds.
It is possible to connect it to 30 meters? Are there any losses?
JaneYu Do you mean connect to a 30 meters long cable? 30 meters is probably too long for a cable to use with this sensor. Two or three meters should be fine though. You may want to teletransmit data, for example using bluetooth or IoT.
ok, I guess I should paste the round part that looks like an electronic circuit. Will it rotate the same or will it remain fixed?
JaneYu The constant value is got from the experiment, and we found the output value is proportional to the wind speed.
JaneYu Thanks you. I need to know what is the highest wind speed that the device supports with out breaking it down ?
