Air Quality Monitor Example

This application demonstrates how can someone use an XPLR-IOT-1 device to get measurement data from a wireless Bluetooth LE sensor, and how can these data be sent to the Thingstream platform via MQTT, and then visualized in a Node-RED dashboard. For this purpose a Wireless Air Quality Monitor Solution is implemented. This solution consists of the elements shown in the picture that follows:

AirQualityMonitorSolution should be here.

In this project a wireless Bluetooth LE sensor is imlemented using a Sensirion SCD41 CO2 sensor in a MikroE HVAC Click board MIKROE-4290. In order to render this sensor wireless you can connect it to a MINI-NORA-B1 Evaluation kit or an XPLR-IOT-1 device (in the latter case you will need two XPLR-IOT-1 devices).

The wireless sensor broadcasts its measurements via Bluetooth LE, and an XPLR-IOT-1 device can be used as a Gateway to pick up those measurements, and send them via a Wi-Fi connection to Thingstream platform using MQTT protocol.

After been transmitted to Thingstream, a Thingstream flow can be created to publish those measurements to a Node-RED dashboard for visualisation.

All these elements are implemented in this project, to provide a complete example.
