Summary Inspired from this http://sheerwind.com/technology/how-does-it-work searching for a proper utilization, I found that it can be helpful for wind speed measuring, using a wind sensor. Additional sensors like temperature or humidity can be attached creating a weather station. https://moderndevice.com/product/wind-sensor-rev-p/ http://moderndevice.com/product/sht21-humidity-and-temp-sensor/ The advantage to this solution is that it captures the wind no matter where the wind blows, because when beating it may change direction. Wind catcher diameter is about 120 mm. Long tube length 130 mm Middle tube length 70 mm (for sensors purpose) Short tube length 30 mm
