Interesting build for a remote pool temperature monitor

Its a cheap build too.  Using an ESP8266 (these have been showing up in alot of projects lately).  The build itself is pretty simple but I wonder if the sensor should be somewhere else in the pool instead of inline with the pump which may change results.  Either way nice build.
