# Cigar Humidor Updates Twitter — Powered by ThingSpeak and Arduino #iot

> Cigar Humidor Updates Twitter — Powered by ThingSpeak and Arduino #iot

Original author: Hans Scharler (source: https://blogs.mathworks.com/iot/2014/04/04/cigar-humidor-updates-twitter-powered-by-thingspeak-and-arduino/)

## Components

- **Arduino Ethernet Shield** x 1 ([docs](https://docs.arduino.cc/retired/shields/arduino-ethernet-shield-without-poe-module))

## Article

[C.A.V.A] has created a cigar humidor application which sends a twitter update to maintain a freshness of a cigar. A humidor stores cigars in a humidity controlled environment to maintain freshness, but this special humidor sends the humidity sensor value to ThinSpeak and alerts twitter when it needs water. The project uses a humidity sensor and an Arduino Ethernet to post the data to the ThingSpeak API.

**Main components**

Arduino Uno, Sensor DHT11, Arduino Ethernet Shield, Display LCD
