mwthewsey 11:b538e73841ae 12 *Temperature, pressure, LDR and time readings are passed into the object using
mwthewsey 11:b538e73841ae 13 *the UpdateData function. A custom message can also be displayed using
mwthewsey 11:b538e73841ae 14 *SendMessage, with the option of returning to enviromental data.
