- Fri Nov 06, 2015 7:30 am #33250 This is a use for an ESP with i2c to RTC and LCD displaying the Environment Sensed via DHT22, this host an Access Point and has a client connection to your router.
The LCD Text can be written to from the Hosted site. the data is displayed via a Table, Graphs and Charts with all data being stored in SPIFFS leaving most of the SRAM free....

The only file management here is to reboot but I have an SDCARD attached and this takes the backup before reboot this is a simpler version to allow the understanding of File IO.

For the Google services the device must be connected to router....

Look at the BBC in the UK for the Sample Output from a slightly larger setup........ESP8266 DDTMonitor.....

http://bbc.in/1LYbwUg

This is the Sketch But please note this is a collection of a lot of peoples efforts most of whom are members of this site and please consider a Donation to the ESP8266.COM Cause(found elsewhere on this site)........

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 512KByte Flash with 64KB SPIFFS can hold 1800 records of 30 bytes (1 temperature + 1 humidity reading + Timestamp) Approx. 54KB

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

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

This will read various sensors  with the Data from the Sensors presented via Web Gauges, Graphs & Tables.....

Setup = DHT22 and an ESP8266 with 512KB Flash i2c LCD + RTC

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  2

......Use 5v to 3v Level Shifters as 5V devices like PIR and HC-SR04 can damage your device.......
