Detailed Description
The MeasurementHandler class forms the link between data generation and data output, and stores settings.
Receives requests from GroveDht22 when a new measurement has been taken or error has occurred. This handler then sends that information on to UsbComms for printing that information to terminal and SdHandler for printing that information to the CSV data file.
This handler also determines if the necessary conditions have been met to send an SMS. This is based on last measurement, the set alert threshold, and time since last alert was sent. An SMS is sent using GprsHandler.
Other requests from inputs asking for current measurement states (such as the latest measurement) may come from UsbComms or GprsHandler. The string inspection and matching is handled here, and responses sent to the data outputs.
Flashes LED4 constantly to inform that normal operation is occurring.
