The Angry Humidor

Just for fun I added an Arduino to a humidor to monitor the temperature and humidity.

This humidor is built on the newest Arduino board, the MKR1000. This board is basically an Arduino Zero with a built in WiFi shield. I added a Adafruit-htu21d-f temperature and humidity sensor and an LED. The LED is coded to flash codes for errors and readings. The Arduino connects to the WPA2 wireless network with the WIFI101 library. I coded the Arduino to take a temperature and humidity reading every hour then it sends the data over HTTPS POST to a Web API service. The Web API calls a stored procedure in AZURE to write the data to the database. This website pulls the data using MVC. A data access object is created and passed to the model, the model populates the view.

Twitter Account

If, for some strange reason, you take the time to Wifi enable a humidor you should create a twitter acount for it. It is the geeky thing to do. The Web API will randomly select 1 out of 100 temperature and humidity readings to send to the twitter API. This method will create a randomly generated disgruntaled tweet that includes the temperature and humidity.
