Joseph Radford 0:2df78a4443cd 16 * \brief The MeasurementHandler class forms the link between data generation and data output, and stores settings.
Joseph Radford 0:2df78a4443cd 17 *
Joseph Radford 0:2df78a4443cd 18 * Receives requests from \a GroveDht22 when a new measurement has been taken or error has occurred. This handler then
Joseph Radford 0:2df78a4443cd 19 * sends that information on to \a UsbComms for printing that information to terminal and \a SdHandler for printing
Joseph Radford 0:2df78a4443cd 20 * that information to the CSV data file.
Joseph Radford 0:2df78a4443cd 21 *
Joseph Radford 0:2df78a4443cd 22 * This handler also determines if the necessary conditions have been met to send an SMS. This is based on last measurement,
Joseph Radford 0:2df78a4443cd 23 * the set alert threshold, and time since last alert was sent. An SMS is sent using \a GprsHandler.
Joseph Radford 0:2df78a4443cd 24 *
Joseph Radford 0:2df78a4443cd 25 * Other requests from inputs asking for current measurement states (such as the latest measurement) may come from \a UsbComms
Joseph Radford 0:2df78a4443cd 26 * or \a GprsHandler. The string inspection and matching is handled here, and responses sent to the data outputs.
Joseph Radford 0:2df78a4443cd 27 *
Joseph Radford 0:2df78a4443cd 28 *
Joseph Radford 0:2df78a4443cd 29 * Flashes LED4 constantly to inform that normal operation is occurring.
