CCS811 이산화탄소 및 TVOC 공기품질 센서

(CCS811 CO2 and TVOC Air Quality Sensor)

본 제품은 CCS811 탑재한 이산화탄소 및 TVOC(Total Volatile Organic Compounds)의 측정이 가능한 공기품질 센서입니다.
CO2는 400-8192ppm, TVOC는 0- 1187ppb 범위의 측정이 가능합니다.
CCS811의 데이터쉬트에 따르면 올바른 센서 데이터 출력을 위해서는 48시간의 통전 테스트와 20분의 런인 타임이 필요합니다. (센서가 올바른 데이터를 출력하기 위해서는 20분간 웜업 시켜주어야 합니다)

Uses of TVOC sensing:
- Testing of materials for chemical emission (that new car smell)
- Indicator of insufficient or poorly designed ventilation
- Identification of high polluting activities
Uses of CO2 sensing:
- Indoor Agriculture including aqua- and hydroponics
- Room occupants and HVAC loading
Features:
- CO2 sensing from 400 to 8192 parts-per-million
- Total Volatile Organic Compound (TVOC) sensing from 0 to 1187 parts-per-billion

- The Australian Government specifically excludes certain compounds (like CO, methane, etc) from the definition of 'TVOC'. It's unclear how universal this is.
