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
