Qwiic 공기 품질/대기압 온습도 센서 -CCS811, BME280
(Qwiic Air Quality Combo Board - CCS811 + BME280)
개요
- 본 제품은 대기압, 습도, 온도, TVOC 가스, eCO2 가스와 같은 환경 데이터를 측정하는 센서입니다.
- TVOC와 eCO2 같은 유해가스를 탐지하는 CCS811과 대기압/온습도를 측정할 수 있는 BME280칩을 탑재하였습니다.
- BME280의 측정데이터를 CCS811에 제공하여 온습도에 따른 보정된 TVOC와 eCO2값을 얻을 수 있습니다.(예제코드 제공)
