CCS811 is a low-power digital gas sensor solution, which integrates a gas sensor solution for detecting low levels of VOCs typically found indoors, with a microcontroller unit (MCU) and an Analog-to-Digital converter to monitor the local environment and provide an indication of the indoor air quality via an equivalent CO2 or TVOC output over a standard I2C digital interface.
This allows the sensor’s output to be used for ASHRAE’s CO2-based VRP ventilation schedule. CO2e units come with 3 VOC level status LEDs on the face of the unit. The total VOC (TVOC) units provide a VOC reading that is the total concentration of all VOCs present in the space within a …
May 05, 2019· You need to use an external sensor, like the Si7021, to get those values. (Otherwise, it uses a middle-of-the-road humidity and temperature to calculate TVOC and C02) Another downside is there is no specification on the accuracy of the device.
What the sensor is actually measuring is the electrical resistance of this metal-oxide layer. This real time measurement and output of resistance is the first step in obtaining our TVOC reading. The change in resistance across the surface of the sensor is directly proportional to the change in …

Thus, a measurement known as TVOC was adopted to measure the overall amount of VOCs in a given space. Total volatile organic compounds (TVOC) is a group of VOCs used to represent the entire pool of pollutants. If you have an air quality monitor with volatile organic compound detection capabilities, you will see your readings in terms of TVOC.
