Hello all,
For my master's thesis in Biology, I am looking into the dispersal potential of maple samaras.
For this I am building a small vertical wind tunnel into which I want to observe the samaras in flight.
I wanted to use the Pi 5 with an HQ camera to record the wind tunnel, as well as an anemometer to record wind speeds.
I'm having trouble finding an anemometer that would fit my needs, especially because I am deeply out of my field with electrical components, so I'm looking for recommendations.
It would need:
To be very precise at low wind speeds, since the difference between one samara and the next reaching floatability is very small.
To fit inside a small chamber (30L x15W x50H cm) as well as being out of the way so as to not disturb the samaras in flight.
Ideally, to be able to connect to the Pi to log the wind speeds in real time without having to check the sensor by hand every time.
I've seen the Wind Sensor Rev. P, but I believe that it needs higher voltage (12V) than given by the Pi, so it would require it's own separate power supply?
Is there anything that could be powered only by the Pi but that would still be precise enough?
Any comment is appreciated,
Jean-Christophe Pomerleau
