Comparison of CO2 sensors MHZ19B and CCS811

MHZ19B CCS811 Both sensors are designed to measure the level of carbon dioxide indoors. The CCS811 sensor has many advantages over MHZ19B significantly smaller size, lover voltage and current, lower price. For comparison, both sensors were connected to ESP8266 development boards with very similar firmware.

Reliability of measurements · Issue 8 · maartenpennings ...

Dec 16, 2018· The MHZ19 is an absolute CO2 sensor, the CCS811 is a relative VOC sensor. That is hard to compare. They really measure different things. By the way, strange to see that several CCS811 spikes coincide with MHZ19 valleys. Your MHZ19 readings are, for me, counter intuitive. The bad air builds up from around 16:00 till 9:00, where it sharply ...
