Please, take a look at a small correction I made within the post http://www.esp8266.com/viewtopic.php?f=19&t=752.
Your script will fail for negative temperatures.

thx for the script.
Tested it with my ESP8266-01.
Changed the OW-Pin to 4 / GPIO2 (New Table for 0.9.4 build 20141222)
Because of getting a coherent value from the DS18B20, this should be OK.

But I have problems with the integrated web-server.
I only see the first line in the browser -> conn:send("<h1> DS18B20</h1>")
The line with the temperature is not sent. (checked the traffic with wireshark)
Masking out the first line, the ESP sends me the second line with the right temperature. Looks like he can send only one telegram???

my ESP8266: ESP-01 V2 / ESP-12E (NodeMCU)
ESP8266 Arduino add-on
Arduino IDE 1.6.5
