Raspberry Pi Humidity and Temperature Sensor and Dashboard

EON is an open-source JavaScript framework designed to facilitate the visualization of IoT sensor readings in real-time by creating interactive charts, maps, and dashboards. The tutorial guides users through setting up a Raspberry Pi Model B with a DHT22 sensor to collect temperature and humidity data, which is then streamed to a live-updating user interface using PubNub. It involves hardware assembly with components like jumper wires, a breadboard, and a resistor, followed by software installation and configuration, including Python, pip, PubNub, and the Adafruit DHT library. Users initialize a PubNub object with unique publish and subscribe keys to stream data continuously, visualizing it on a line graph for temperature and a gauge chart for humidity using EON's capabilities. The tutorial emphasizes ease of implementation with EON's diverse chart options, which can be customized and are compatible with web browsers, enhancing the potential for various embedded applications.
