Description

The AIR QUALITY 2 CLICK board integrates a sophisticated metal-oxide (MOX) based iAQ-Core sensor, which uses predictive algorithms to estimate equivalent CO2 (eCO2) and Total Volatile Organic Compound (TVOC) levels. The sensor element is protected by a permanent filter membrane and plastic cap, ensuring long-term stability and protecting it from dust and large particulates.

Designed for the mikroBUS standard, this click board offers plug-and-play compatibility with a wide range of host boards from Mikroe and other manufacturers. Its low power consumption and digital I2C output make it ideal for continuous monitoring in space-constrained and power-sensitive applications, providing reliable air quality data without requiring complex signal conditioning.

Key Features

  • iAQ-Core Sensor: Provides calibrated eCO2 and TVOC equivalent readings based on detected VOCs.
  • Dual Voltage Operation: Supports both 3.3V and 5V power supplies for broad microcontroller compatibility.
  • Digital I2C Interface: Simplifies wiring and communication, requiring only two data lines.
  • Protected Sensing Element: Features a permanent filter membrane and protective cap to extend sensor life.
  • Low Power Consumption: Optimized for battery-powered and always-on IoT applications.
  • Standard mikroBUS Form Factor: M-size (42.9 x 25.4 mm) for easy mounting on carrier boards.
  • Predictive Algorithm Output: Delivers eCO2 and TVOC equivalent values, not raw gas concentrations.

Applications

  • Smart thermostat and HVAC system air quality feedback control.
  • Indoor environmental quality monitoring in smart home and office IoT devices.
  • Portable air purifier and ventilation system performance monitoring.
  • Embedded air quality sensing in consumer electronics and wellness products.

Frequently Asked Questions

What does the iAQ-Core sensor on this board actually measure?

The iAQ-Core sensor detects a broad range of Volatile Organic Compounds (VOCs) using a metal-oxide (MOX) sensing element. It then uses an internal algorithm to output two predictive values: an equivalent CO2 (eCO2) concentration in ppm and a Total VOC (TVOC) equivalent concentration in ppb. It does not measure specific gases like CO2 directly.

What is the correct wiring for the I2C interface?

Connect the board's SDA and SCL pins to the corresponding I2C pins on your microcontroller (e.g., Arduino, Raspberry Pi). Ensure a common ground connection. The board is powered via the mikroBUS VCC pin, which can accept either 3.3V or 5V. No additional pull-up resistors are required as they are integrated on the click board.

Can the protective filter cap on the sensor be removed?

No, the plastic cap and the underlying filter membrane are permanent, protective components. They shield the sensitive metal-oxide layer from dust, fibers, and direct physical contact, which could damage or contaminate it. Removing or touching the membrane will void the sensor's functionality and calibration.

Is this sensor suitable for outdoor or industrial gas leak detection?

No, this sensor is specifically designed for indoor air quality assessment. Its measurement ranges (eCO2: 450-2000 ppm, TVOC: 125-600 ppb) are optimized for typical indoor environments like homes and offices. It is not designed for detecting specific toxic gas leaks, high-concentration industrial pollutants, or for use in harsh outdoor conditions.
