Objective is to construct, calibrate, and document a system for measuring wind speed using deployable sensors, with data collected using a multichannel analog-to-digital converter system that runs on a high end computer.
...
Sensor is revision P wind sensor from Modern Devices, https://moderndevice.com/products/wind-sensor-rev-p .
Schematic diagram is here: WindSensorRevPschematic.pdf
Sensors will be mounted inside carbon fiber tube with a clamp at other end for DB-9 connector.
...
- cut carbon tube in half.
- attach DB-9 connector to flange with two 4-40 screws. Use standoffs if it doesn't clear ID.
- feed ribbon cable through tube, and plug other end into sensor. Wire will have to be folded carefully into tube. Use DB-9 jack screws (4-40) to mount connector.
- test electrical connections and functionality
- glue in both the connector flange and the sensor using 5 minute epoxy or silicon RTV
- add mount clamp at midpoint
DB-9 connector on sensor is FM. Need long-ish cables to run inside the dome, running to DB9 connector at computer end.
...
Need to store data at one reading per second, perhaps averaging over multiple readings. It would be nice to provide a panel with windspeeds,see for example https://pi-plates.com/displaying-data-with-a-virtual-meter/
