Credits to Stefan Thesen and The Guy's at .......http://www.ESP8266.com
With the use of http://espressif.com/new-sdk-release

The ESP8266 Arduino Reference http://arduino.esp8266.com/versions/1.6.5-1160-gef26c5f/doc/reference.html

With this release and a 1MByte Flash with 512KB SPIFFS can hold 3328 records of 120 bytes long Approx. 390KB

Set up an account at http://smtp2go.com
Encrypt your Password & Username using https://www.base64encode.org/

This evolution is the product of the Environment Monitor...... 
environmental.monitor.log@gmail.com

See a feed from 2 DHT11's on twitter at http://twitter.com/DDTMonitor

This will read various sensors and send an Email at a time or Sensor Condition
With the Data from the Sensors presented via Web Gauges, Graphs & Tables.....

Setup = 2 * DHT11 + BMP180 and an ESP8266-07 with 1MB Flash

There are various pins used to load boot code so if you change pins and it does not boot this is WHY!!

I2C  GPios 4 & 5
DHT  GPio  14 & 16


To Index to a data point, each record is 64 bytes, there ar place holders to count in the string record
to select an individual data point.
The SPIFFS Record selction.......to allow reading/modifying a value....... 

File dataFile1 = SPIFFS.open("/humidlog.CSV", "r"); //  a = append/modify, r = read or create w = write
  if(!dataFile1.seek(0, SeekSet))   //  Other Commands are seekCur or seekEnd
  {
    Serial.println(F("Rewind fail"));
    dataFile1.close();
  }
 stringholder = dataFile1.readStringUntil("[");  //Start of Record idexed to with file offset currently=0
__________________________________________________________________________________________________
......Use 5v to 3v Level Shifters as 5V devices like PIR and HC-SR04 can damage your device.......
