Joseph Radford 0:2df78a4443cd 2 * Project: Humidity SMS Alert
Joseph Radford 0:2df78a4443cd 3 * Author: Joseph Radford
Joseph Radford 0:2df78a4443cd 4 * Date start: January 2016
Joseph Radford 0:2df78a4443cd 5 * Date mod:
Joseph Radford 0:2df78a4443cd 6 * Target: Arch GPRS V2
Joseph Radford 0:2df78a4443cd 7 * Peripherals: SD Card
Joseph Radford 0:2df78a4443cd 8 * SIM Card
Joseph Radford 0:2df78a4443cd 9 * Grove Humidity and Temperature Sensor Pro (DHT22 on a breakout board)
Joseph Radford 0:2df78a4443cd 10 *
Joseph Radford 0:2df78a4443cd 11 *
Joseph Radford 0:2df78a4443cd 12 * Takes intermittent readings from the humidity temperature sensor. These are written to a timestamped CSV file
Joseph Radford 0:2df78a4443cd 13 * on the SD card and printed over serial if there is a connection to a terminal window (Screen on Linux, Putty on Windows, etc)
Joseph Radford 0:2df78a4443cd 14 *
Joseph Radford 0:2df78a4443cd 15 * When conditions have been met, an SMS alert is sent notifying the recipient of the last sensor readings.
Joseph Radford 0:2df78a4443cd 16 *
Joseph Radford 0:2df78a4443cd 17 * States can be requested, and configurations changed, by sending requests over USB serial or SMS.

Joseph Radford 0:2df78a4443cd 32 *
Joseph Radford 0:2df78a4443cd 33 * 10/04/2016 v0.0.1 - Writes timestamped humidity data to an SD card
Joseph Radford 0:2df78a4443cd 34 *
Joseph Radford 0:2df78a4443cd 35 * Issues:
Joseph Radford 0:2df78a4443cd 36 * Stops communicating over USB after ~10 mins.
Joseph Radford 0:2df78a4443cd 37 * Will not work if USB not present.
Joseph Radford 0:2df78a4443cd 38 * Will not work if SD card is not present
Joseph Radford 0:2df78a4443cd 39 * GPRS yet to be implemented
Joseph Radford 0:2df78a4443cd 40 * RTC is set to 01/01/2000 00:00:00 at startup. No way of setting it yet.
