To measure the temperature and humidity by using DHT11 sensor

The weather station is a prototype and you must not expect 24/7 operation neither accurate measurements. Improvements are coming soon. Check this channel for data analysis: https://thingspeak.com/channels/279384

uses MAX6675 as temperature probe front end. Hardware is not yet finish, waiting for PCB and some parts.
