✅ This type of digital sensor is used for the measurement of changes in volatile organic compounds, in particular carbon dioxide (CO2). The module is equipped with a CJMCU-811 CCS811 CO2 Air Quality Metal Oxide Gas Sensor.
✅ The sensor is characterized by a relatively low power consumption and can therefore also be used in battery-powered devices.
✅ This device is mainly used for monitoring indoor air quality and can be read by microcontrollers via the I2C interface.
✅ Due to its complex design, the module is very sensitive and able to accurately calculate the share of eCO2.

Description

Metal oxide (MOX) sensors for monitoring indoor air quality. The I2C slave interface can be directly connected to the higher-level control system.

Features

This breakout board provides a convenient introduction to the use of the popular CCS811, a digital air quality sensor module that measures a wide range of volatile organic compounds (VOCs), especially equivalent carbon dioxide (eCO2).

Technical data

Power supply recommended 3.3 V
Power consumption up to 60mW
IIC communication frequency 400KHz
TVOC detection range 0 ~ 1187ppb
eCO2 detection range 400 ~ 8192ppm

Alternative address selection

You can select the alternate I2C address by pulling the ADD pin HIGH, so you can connect two of these sensors to the same bus.
