First step of integration between software (AR) and hardware is complete. Now, instead of the device simulator program, there’s an actual device. Using a microcontroller with Wifi connectivity for preliminary testing. The device connects to MQTT, sends sensor data (randomized for now), and subscribes to the relevant topics. For testing in the field, the device will connect to an access point (aka hotspot) from a phone to send the data.  Future versions will use a microcontroller with cellular connectivity in the field. The next steps for software are to write a python program that logs all messages on the MQTT broker to a csv file. The next steps for hardware are to find some sensors I have around and add some LEDs, a speaker, and make a board with it. Integration with the map will also need to be completed at some point in the future.
