Z_IAQ
Overview
Z_IAQ is a board based on BME688 Air Quality Sensor from BOSCH.
The Z_IAQ features 3 RGB LEDs which indicates the indoor air quality based on the measured gas concentration. The BME688 also incorporates humidity, pressure and temperature sensors.
The Z_IAQ includes the following elements:
- A Bluetooth Low Energy (BLE) MCU to communicate with BLE capable devices like smartphones
- A component for programming and debugging via USB
- Flash with drag and drop
- Virtual port com via USB
- USB interface for power supply
