MCU-8118 CCS811 HDC1080 Module: Carbon Dioxide , VOC, Temperature, and Humidity Sensor

Description : CCS811 HDC1080 Module: Carbon Monoxide, Temperature, and Humidity CO VOC Air Quality Detection Module Size: 15mm * 21mm The CCS811 HDC1080 module is a Sensor System-on-Chip (SSoC) gas sensor + temperature and humidity sensor, which utilizes low-power sensing technology to detect indoor Volatile Organic Compounds (VOCs). Looking at the onboard structural diagram of the CCS811 HDC1080 module, we can see that it is not a simple sensor; it also integrates an internal MCU. This gives the sensor onboard processing capabilities, allowing it to provide equivalent CO2​ (eCO2​) levels or Total Volatile Organic Compound (TVOC) metrics without host intervention. Compared to solutions that use separate gas sensors and MCUs, the CCS811 can save on hardware bill-of-materials (BOM) costs and reduce board space by up to 60%. HDC1080 Low-Power, High-Precision Digital Humidity Sensor with Temperature Sensor The HDC1080 is a digital humidity sensor with an integrated temperature sensor that delivers excellent measurement accuracy with ultra-low power consumption. The HDC1080 supports a wide range of operating supply voltages and offers low-cost, low-power advantages for a variety of common applications compared to competing solutions. The humidity and temperature sensors are factory-calibrated. Relative Humidity Accuracy: ±2% (typical) Stability: High stability in high humidity Measurement Resolution: 14-bit Sleep Mode Current: 100nA
