Raspberry Pi 2 IoT: Thingspeak & DHT22 Sensor

This project uses a Raspberry Pi 2 to collect temperature and humidity data from a DHT22 sensor, which is then uploaded to the ThingSpeak Internet of Things platform to be displayed in real-time. This write-up is primarily intended to serve as documentation for the project, but may also be of use as a tutorial for others. It assumes a beginner skill level and that you are running the Raspberry Pi without a screen (referred to as a headless setup).”
