Description: Module size: 15mm*21mm CJMCU-8118 gas sensor, on chip system chip (SSoC) + temperature and humidity sensor, uses low power sensing technology to detect volatile organic compounds (VOCs) in the room. CJMCU8118 onboardCCS811The 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 (TVOCIndex. 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 low temperature and high precision digital humidity sensor with temperature sensor DC1080 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. The relative humidity accuracy is + 2% (typical) The temperature accuracy is + 0.2 degrees C (typical value) Excellent stability under high humidity 14 bit measurement resolution The sleep mode current is 100nA Package included: 1 x CJMCU-8118 CCS811 HDC1080 Carbon Monoxide CO VOCs Temperature And Humidity Gas Sensor
