Comparison of CO2 sensors MH-Z19B and CCS811 | Andrey …

Jun 10, 2020· Both sensors are designed to measure the level of carbon dioxide indoors. The CCS811 sensor has many advantages over MH-Z19B - significantly smaller size, lover voltage and current, lower price.. For comparison, both sensors were connected to ESP8266 development boards with very similar firmware. Readings were collected every 10 seconds and sent by MQTT protocol to a Raspberry PI …

mh-z19 · PyPI

Mar 24, 2021· Features about calibration (both MH-Z19 & MH-Z19B), detection range change (MH-Z19B) and ABC logic on/off(MH-Z19B) are implemented at version or later. I'm afraid I've just only implemented these without test due to lack necessary devices and apparatus for the test, fx: standard concentration CO2 gas, also MH-Z19B module.

MH-Z19 & MH-Z19B

The Chinese datasheet for the JST MH-Z19B version (more detailed): MH-Z19B JST. Auto Calibration: The MH-Z19 is a sensor that is designed to be powered on and rarely turned off. The sensor calibrates over time (if autocalibration is on) using the lowest CO2 observed in the prior 24 hours). After 3 weeks, a value is stored with an accuracy ...
