CCS811 Carbon Dioxide CO2 Temperature And Humidity Sensor

Description

Description: Module size: 15mm x 21mm Power supply: 3.3V CJMCU-8118 a gas sensor chip system chip (SSoC) + temperature and humidity sensor, using low-power sensing technology to detect indoor volatile organic compounds (VOCs). CCS811 CJMCU8118 board schematic structure of the figure we can see that this is not a simple sensor, it has integrated MCU, the sensor has an onboard processing capability, without host intervention, can provide the equivalent level of carbon dioxide or total volatile organic compounds (TVOC) index. At the same time, with the use of separate gas sensors and MCU solutions, CCS811 can save equipment inventory costs as well as up to 60% of the total area of the board. The relative humidity is 2% (typical) Temperature accuracy of + 0.2 C (typical) Excellent stability under high humidity 14 bit resolution Sleep mode current is 100nA
