Mar 24, 2021· 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.

Carbon Dioxide Sensor MH-Z19b - Part 1 - Hardware design ...

Jun 10, 2019· Carbon Dioxide Sensor MH-Z19b - Part 1 - Hardware design. Some time ago I have purchased online carbon dioxide (CO2) sensor module MH-Z19b. It’s a cheap and very simple sensor with the UART interface allowing concentration measurement in the range up to 5000ppm. The normal level of CO2 concentration is considered about 400-1000ppm.

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 …
