Air Quality Monitor

This Arduino project read data from BM68x sensor and use BSEC library to get IAQ (Indoor Air Quality) data.

Hardware

• Arduino MKR WiFi 1010
• Arduino MKR IoT Carrier (rev.1)
• BME688

Software

• Bosch BME68x library (for sensor data)
• Bosch BSEC2 library (for IAQ calculation)
• Adafruit DotStar (for RGB LEDs)
• Adafruit ST7735 and ST7789 Library (for TFT display)
• SD (for SD card)
• Arduino_MCHPTouch (for touch buttons)

Please note that you can include the Arduino_MKRIoTCarrier library to have a unified object for accessing the peripherals of the carrier.

Wiring

MKR IoT Carrier

Connect the MKR WiFi 1010 to the MKR IoT Carrier.

BME688

Connect the BME688 sensor to the Arduino board using the I2C interface.

Please note that the ADDR pin is used to select the I2C address of the sensor. If ADDR is connected to GND, the address is 0x76, 0x77 otherwise.

Usage

This project is configured to work with PlatformIO. You can use the platformio.ini file to configure the project settings.

1. Open the project in PlatformIO.
2. Install the required libraries.
3. Build and upload the project to the Arduino board.

Please note that you need to configure the bsec_iaq.config file with the correct sensor settings. You can use the BSEC integration guide to generate the configuration file.
