# Title: Air Quality 2 Click Board™


## Description: The Air Quality 2 Click Board™ carries the iAQ-Core Indoor Air Quality sensor that measures VOC (volatile organic compounds) levels and provides CO2 equivalent and TVOC (total volatile organic compounds) equivalent predictions. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over I2C. IAQ-CORE SENSOR The sensor is protected by a plastic cap and a filter membrane. This membrane should not be removed or touched. The sensing range for CO2 equivalents is from 450 to 2000 ppm (parts per million), and from 125 to 600 ppb (parts per billion) for TVOC equivalents. KNOW EVERYTHING IN 5 MINUTES It takes only 5 minutes for the first functional reading after start up time. After the sensor is powered on, you don't have to wait for it to calibrate. You'll have all the readings you need in less time than it takes to make a cup of coffee. ABC - AUTOMATIC BASELINE CORRECTION iAQ-Core sensor has Automatic Baseline Correction (ABC), which means that you don't need to make any further calibration. You'll be able to use it for many years in a normal indoor environment. LOW POWER CONSUMPTION With low power consumption (maximum of 9mW in pulsed mode and 66mW in continuous mode) Air quality 2 click is ideal for Smart Home applications and IoT projects and devices that require long battery life. VOC OR VOLATILE ORGANIC COMPOUNDS Volatile organic compounds or VOCs are organic chemicals. They have very high vapour pressure at room temperature, and some of them can be harmful to human health. These chemicals are carbon-based (formaldehyde, toluene, benzene, etc.) and they got the name "volatile" from the fact that they become gases at room temperature. They are emitted from various products, like hairspray, household cleaning products, paint, or air freshener, that we use every day. C02 EQUIVALENT CO2 equivalent or CO2e, represents a unit of measurement for the amount of CO2 present in some "greenhouse gas".
