CJMCU-811 CCS811 Indoor air quality monitoring digital gas sensor
The CJMCU-811 is an ultra-low-power digital gas sensor that integrates a CCS801 sensor and an 8-bit MCU with an analog-to-digital converter (ADC) to detect indoor air quality, including carbon monoxide (CO) and a wide range of Volatile Organic Compounds (VOCs).
Air quality sensor CCS811 features:
Ultra-low power consumption can be used in battery-operated equipment
High sensitivity, fast heating
The intelligent algorithm calculates TVOC / eCO2 values
Output I2C signal, direct communication with the main system
The main features of the air quality sensor CJMCU-811:
Metal oxide (MOX) sensors for monitoring indoor air quality
An 8-bit MCU is integrated to run the first-level algorithm
Integrated 12-bit ADC for sensor readings and digitized conversions
I2C slave interface can be directly connected to the host system
Reset / interrupt control



As ccs811 production is reduced and delivery is delayed, the terminal equipment originally designed with ccs811 is facing severe delivery difficulties. For this reason, sciosense (formerly AMS) released the latest VOC sensor: ens160. This sensor is a digital metal oxide multi gas sensor solution based on metal oxide (MOX) technology and four MOX sensor elements. Each sensor element has an independent hot plate control to detect a variety of gases, such as volatile organic compounds (VOC) including ethanol, toluene, hydrogen and nitrogen dioxide, with excellent selectivity and accuracy. For indoor air quality applications, ens160 supports intelligent algorithms to digitally process raw sensor measurements on a chip. These algorithms calculate CO2 equivalent, TVOC and different air quality indicators (AQIS), and perform humidity and temperature compensation and baseline management. Many users who have been using ccs811 before have started to choose to replace it with ens160
