This application demonstrates the display of real-time sensor data from a wireless microcontroller to AR application. It was written using NodeJS, AR.JS, A-Frame, Socket.io and the MQTT communications protocol. The micro-controller is an ESP8266 with an accelerometer and DHT11 temp/humidity sensor. Sample applications might include location-based crop monitoring, building inspection or anything that requires location-based data gathering.
