CCS811+HDC1080+BMP280 Carbon Dioxide Temperature, Humidity and Height Three-in-one Sensor
CJMCU-8128 gas sensor, chip-on-chip system (SSoC) + temperature and humidity sensor, uses low power sensing technology to detect volatile organic compounds (VOCs) in the room.
CJMCU8118 onboard CCS811The structure diagram 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, the CCS811 can save material inventory costs of the device, and account for up to 60% of the board area.
HDC1080 is a digital humidity sensor with an integrated temperature sensor that provides excellent measurement accuracy over ultra-low power consumption. The HDC1080 supports a wide range of operating power supplies, and offers a low cost and low power advantage for a wide range of applications compared to competing solutions. The humidity and temperature sensors are factory calibrated.
