sensor arduino mega co2 cjmcu 811

The sensor you are referring to is, indeed, quite inexpensive and that is mostly because it is not, in fact, an actual CO2 sensor. It''s a VOC (volatile Organic Chemicals) sensor (thing paint fumes, etc.) which does eCO2, which means Equivalent CO2. It basically infers the CO2 concentration from other factors rather than sensing it directly. These eCO2 sensors can be off anywhere from 1550% ...

20211115· This sensor from AMS is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C.

Keyestudio CCS811 carbon dioxide, air quality sensor mainly uses the CCS811 chip. It is an ultralowpower miniature digital gas sensor that can detect a wide range of volatile organic compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. Equivalent carbon dioxide (eCO2) is measured in the range of 400 to 29206 ppm (parts per million), and various volatile ...

20140203· The MG811 sensor is basically a cell which gives an output in the range of 100600mV (400—10000ppm CO2). The current sourcing capability of the cell is quite limited. The amplitude of the signal is so low and the output impedance of the cell is so high that a signal conditioning circuit is required between the sensor and microcontroller’s ADC input. The output voltage of the sensor in ...

From CCS811 CJMCU8118 board schematic structure of the figure we can see …

CJMCU811 is a digital gas sensor which is low power consumption, it can work in battery work equipment. It integrates CCS801 sensor and 8bits MCUs (with analogtodigital converters (ADCs)), can be used to run the firstlevel algorithm. Meantime, it integrates 12bits ADC, so that can be applied for reading of sensor and digitized conversions.

I am observing large spikes in CO2 and TVOC measurements using the CJMCU811 sensor. When plotted it looks like this: Nothing particular is happening around the sensor at those moments of spikes, I''m not breathing on the sensor etc. I use Arduino Uno with the following code:

20181220· CCS811 is a lowpower 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 AnalogtoDigital 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.
