MHZ19 NDIR infrared gas module is a common type, small size sensor, using nondispersive infrared (NDIR) principle to detect the existence of CO 2 in the air, with good selectivity, nonoxygen dependent and long life. Builtin temperature sensor can do temperature compensation; and it has UART output and PWM output. It is developed by the tight integration of mature infrared absorbing gas detection …
20210506· Hi there everyone, I’m new this this forum and fairly new to Arduino. I’m having and issue getting my MHZ19B CO2 sensor to read in my serial monitor. I’ve tried looking at many different examples of code that others have posted in their success stories. When I open my serial monitor, all I see is that the sensor is preheating. Nothing after that. The sensor needs about 3 minutes to heat ...
20210324· Features about calibration (both MHZ19 MHZ19B), detection range change (MHZ19B) and ABC logic on/off(MHZ19B) 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 MHZ19B module. If you have these devices or apparatus and try to use …
20210506· Firstly I bought 1 piece mhz19. Tried to run it many days (maybe 67 days). I had not get any data than i decided to buy 1 more mhz19 and mq135.

20160605· There are quite a lot of CO2 sensors: MG811(~40), MHZ14 WINSEN(~40), MHZ19 WINSEN(~30), K30(~85), VERNIER CO2BTA(~330). NDIR (nondispersive infrared) CO2 sensor is the most common type of sensor used to measure CO2, which has good precision and low power consumption. Prices are very various. MHZ19 sensor has good characteristics and great price, so I decided to buy this one. MHZ19 ...
20210612· The MHZ19 library by Jonathan Dempsey is, as the name suggests, written specifically for the MHZ19 sensors. It works with both the B and C variants. My attempt to use it for the MHZ14 failed. The MHZ19 library is characterized by the fact that it uses many of the undocumented commands, such as the query of the range or the firmware version. Thanks to the many example sketches, it is easy ...
20200629· CO2 sensors need to be calibrated now and then, the default for MHZ19B being Automatic Baseline Calibration (ABC) to lowest measured values every now and then (day?), which would be assigned the ballpark outside CO2 figure of 400 ppm. This is far from accurate and cannot be used to monitor rise of CO2 in the atmosphere, but is tolerable for inside air quality measurement, where most …
