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 =
Physical Property Measured =
converted to binary =
converted to decimal =
Converted value in output units =
max no. of values
req min value
req max value
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)
11 byte string conversion calculations to binary number format
number position in byte string =
hex value @ position in byte string =
converted to binary value @ position in byte string =
