LoRaWAN Data Format: MeteoWind IoT LoRaWAN wireless message bit string verifier calculator                        
This calculator is meant for quick message decoding for MeteoWind IoT wind transmitters that send a bit-shifted string.                                              
MeteoWind IoT message format 10 byte                                                  
Input XX byte or longer string (hex) =                                                  
hex converted to binary =                                            
bit shifting string start position = 1st bit

FINAL CALCULATED OUTPUT VALUES =                                            
    Wind_ave value is mean (average) wind speed for the 10 minute interval.                                                  
    Wind_3sgust value is gust value per WMO (maximum rolling 3 second average wind speed)                                                  
    Wind_3smin value is minimum rolling 3 second average wind speed.                                                  
    Wind_stdev value the wind speed standard deviation.                                                  
    Dir_ave is the mean (average) wind direction for the 10 minute interval.                                                  
    Dir_3sgust is the wind direction of the maximum gust wind speed (Wind_3sgust).                                                   
    Dir_stdev value the wind direction standard deviation.                                                  
    3sgust_time value is the elapsed time in multiple of seconds after start of logging interval, time resolution = 5 sec.                                                  
    Vector/Scalar value of wind speed & direction,  Scalar=0(default), Vector =1.                                                  
    Alarm sent? value indicates whether alarm was activated during the current time interval, alarm was not sent during the last logging interval=0(default), at least one alarm was sent during the last logging interval =1.                                                  
    Sensor Error or N/A = Maximum possible bit value for each measurand in binary = 111111…. (FFFFF…. In hex) signifies measurement error code.
