Hello! I have a question with a product that I buy with you. It is the product "Anemometer Wind Speed Sensor w / Analog Output Voltage". In the description says its measurement range is from 0.4V (0 m / s wind) up to 2.0V (for 32.4m / s wind speed), but the technical details says the range is: Testing Range: 0.5m / s to 50m / s. What is the maximum range ? 32.4m / s wind or 50m / s ? https://www.adafruit.com/product/1733
thanks

Re: Anemometer Wind Speed Sensor w/Analog Voltage Output
the voltage output range is specified up to 32m/s, 50m/s is probably the max suggested (still works) and 70 m/s its heading towards being damaged.

Re: Anemometer Wind Speed Sensor w/Analog Voltage Output
You just need to do an analogRead() of the pin you have the output connected to and convert to mph.
I'll see if there is more info available.To use, connect the black wire to power and signal ground, the brown wire to 7-24VDC (we used 9V with success) and measure the analog voltage on the blue wire. The voltage will range from 0.4V (0 m/s wind) up to 2.0V (for 32.4m/s wind speed). That's it! The sensor is rugged, and easy to mount. The cable can easily disconnect with a few twists and has a weatherproof connector.

Re: Anemometer Wind Speed Sensor w/Analog Voltage Output
Crunching the numbers, that comes to:
- 50mV =~ 1 meter per second
- 22mV =~ 1 mile per hour
- 15mV =~ 1 foot per second
- 1mV =~ 2cm per second
- 1mV =~ 3/4" per second
- 50mV =~ 1 meter per second
- 22mV =~ 1 mile per hour
- 15mV =~ 1 foot per second
- 1mV =~ 2cm per second
- 1mV =~ 3/4" per second

Re: Anemometer Wind Speed Sensor w/Analog Voltage Output
Adafruit Hello friends, I have a question please help me!!.
what happens is I do not understand very well the descricion Connect the wires if they could help me clarify this part I would be very grateful to them "To use, connect the black wire to power and signal ground, the brown wire to 7- 24VDC (9V we used with success) and measure the analog voltage on the blue wire. "
postscript: sorry for my English

Re: Anemometer Wind Speed Sensor w/Analog Voltage Output
- Connect the black wire to GND.
- Connect the brown wire to VCC (7v - 24v)
- Read the output from the blue wire.
- Connect the brown wire to VCC (7v - 24v)
- Read the output from the blue wire.

Re: Anemometer Wind Speed Sensor w/Analog Voltage Output
The cable is too short. How long can it be and what connector and cable should I buy?

@oguime How long do you need it to be? You could solder the wires and heat shrink the connection or use something like this http://raychem.te.com/documents/webserv ... &docId=927

Re: Anemometer Wind Speed Sensor w/Analog Voltage Output
I need a cable that is at least 4m long.
I will solder if there is no other choice... I have the anemometer with me, but could not find the parts.
The connector is X12K4P and cable AO84147 AVVR 3x0.3mm2 300/300V.

Re: Anemometer Wind Speed Sensor w/Analog Voltage Output
You can use any kind of wire to extend the lines that come out of the anenometer, and any kind of connector between the existing wires and the extension.
If you want a simple but durable extension, use 20 gauge wire and bullet-style automotive wiring connectors.

Supplied 12 volts to brown and ground to black. I read .4 volts (as expected) between blue and black.
However it does not seem to increase during rotation.
Any advise,
Thanks, George

Re: Anemometer Wind Speed Sensor w/Analog Voltage Output
@George that does not sound right. Are you using a meter to test? How fast are you spinning it?

Re: Anemometer Wind Speed Sensor w/Analog Voltage Output
Hello,
I am very confused about the voltage returned by the Anemometer.
I have purchased a 9v battery, connected the black wire to the (-) side, connected the brown wire to the (+), and connected the blue wire to Arduino Analog Pin A0.
I assume this correct!
Then, this is my Arduino code:
const int analogInPin = A0;
int sensorValue = 0;
float sensorVoltage = 0.0;
void setup()
{
Serial.begin(9600);
}
void loop()
{
sensorValue = analogRead(analogInPin);
sensorVoltage = sensorValue * .004882814; // Convert from 0...1024 to 0...5v
Serial.print("Sensor Value: ");
Serial.print(sensorValue);
Serial.print("\t");
Serial.print("Sensor Voltage: ");
Serial.print(sensorVoltage);
delay(100);
}
The Anemometer is at rest, but the values are:
Sensor Value: 268 Sensor Voltage: 1.31
Sensor Value: 265 Sensor Voltage: 1.29
Sensor Value: 266 Sensor Voltage: 1.30
Sensor Value: 268 Sensor Voltage: 1.31
Sensor Value: 245 Sensor Voltage: 1.20
Sensor Value: 277 Sensor Voltage: 1.35
I was expecting ~0.4v as stated in the product description.
