Schematics

AirLert Schematic

Shows the basic interconnects between the hardware. XMC1300 Boot Kit and Arduino Uno are powered via USB. SGP30 is connected to the Notecarrier via I2C Quiic cable. Notecarrier and XMC1300 are connected via I2C jumpers. A single cable connects the XMC1300 to the Arduino Uno. The radar is connected with 2 jumpers (TD/PD) to the XMC1300 Boot kit.

Code

AirLert Arduino sketches

Two sketches: one for the XMC Boot Kit 1300, which reads the sensor data and sets a trigger pin if the CO2 value exceeds a threshold. The second sketch is for the Arduino Uno with the MP3 shield, which plays a .wav file warning message if the pin is triggered.
