Este modulo integra dos sensores en una placa. Cada uno de ellos puede ser leído independientemente a través del I2C
El HDC1080 es un sensor de temperatura y humedad de alta precisión y bajo consumo.
El CCS811 es un sensor de calidad de aire de bajo consumo. Usa un sensor de metal Oxide (MOX) para medir el equivalente total de componentes volátiles orgánicos (TVOC) y contenido equivalente de CO2 . El modulo incluye un micro controlador (MCU) para corregir las lecturas de gas en función de la temperatura y humedad ambiente.
