The Air Quality Sensor v1.3 from Seeed Studio is a compact, low power consumption sensor for detecting multiple air quality parameters in the environment. It measures temperature, humidity, and volatile organic compounds (VOCs) in the air. It utilizes a capacitive sensing method and an advanced MCU processing unit to give accurate and fast readings. The sensor also features multiple interfaces, including SPI and I2C, for easy connection and communication. The sensor can be used for applications such as health care, indoor air quality monitoring, and pollution monitoring. It also has a built-in LED to indicate the quality of the environment.
