For this project, Bluetooth Low Energy USB dongle called BlueIO is used, which will act as a central device to retrieve data. HibouAir will serve as a peripheral device to transmit the data. The is simple to use and can be used for other purposes such as showing real-time air quality data; temperate, humidity, pressure, particle matters etc. The .cs file associated with this will have the following code. Source code is available at https://github.com/smart-sensor-devices-ab/bluetooth_realtimedata_csharp In this script, we are only showing how to plot Ambient Light Sensor (ALS) value in lux and plot it on the chart.
