OPEN Data Format: MeteoHelix IoT Sigfox & LoRaWAN wireless message bit string verifier calculator
This calculator is mean for quick message string payload decoding for MeteoHelix IoT micro weather stations that send a 11 byte bit-shifted string.
OPEN PROTOCOL START BIT (Type) = 1
Input 11 byte string (hex) =                          
hex converted to binary =                          
bit shifting string start position =

T_max & Irr_max values are added to the Temperature and Irradiation readings which are currently set to be 10min averages of 15sec measuring intervals. T_min is subtracted from the Temperature reading.
Sensor Error or N/A = Maximum possible value for the physical property which in binary = 111111…. (FFFFF…. In hex)
