Decoder for the TTN Application

function Decoder(bytes, port) {
  var decoded = {};
  decoded.t = (bytes[0]) | (bytes[1] << 8 ) | (bytes[2] << 16 ) | (bytes[3] << 24)
  decoded.t = decoded.t / 100
  decoded.p = (bytes[4]) | (bytes[5] << 8 ) | (bytes[6] << 16 ) | (bytes[7] << 24)
  decoded.p = decoded.p / 100
  decoded.h = (bytes[8]) | (bytes[9] << 8 ) | (bytes[10] << 16 ) | (bytes[11] << 24)
  decoded.h = decoded.h / 100
  decoded.v = (bytes[12]) | (bytes[13] << 8 ) | (bytes[14] << 16 ) | (bytes[15] << 24)
  decoded.v = decoded.v / 1000
