Architecture proposal for real-time sensor monitoring using IoT and Augmented Reality

In this work, a greenhouse data acquisition system is proposed using the IoT protocol called MQTT, which is implemented in a Raspberry Pi configured as an MQTT broker. The augmented reality application is implemented in Unity for Android cell phones, when the cell phone camera detects the designed target, the application will create an informative 3D model of a greenhouse, in which the values of humidity in the soil, temperature, and ambient humidity, in addition to the level of carbon dioxide present in the air. These values add a dynamic feature that enhances the experience of a virtual laboratory or provides a distinctive detail to other projects that have augmented reality.
