20170815· Hello All Was just testing the MHZ19 module and am having some issues. Using UART to connect to esp8266 define CO2_TX D6 define CO2_RX D7` also powered using 3V and Ground. Got it setup fine and connected to blynk server…it says 1 for a minute then around 420 ppm which is probably about right but after about 5 minutes it just goes to 5000 ppm and stays there. its a 5000 ppm sensor …

The Englisih datasheet for the MHZ19: MHZ19. The English datasheet for the nonJST MHZ19B version: MHZ19B NONJST. The Chinese datasheet for the JST MHZ19B version (more detailed): MHZ19B JST. Auto Calibration: The MHZ19 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 ...
MHZ19B 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 compensation; and it has UART output and PWM output. It is developed by the tight integration of mature infrared absorbing gas detection technology, precision …

Profile MHZ19 NDIR infrared gas module is a common type, If you''re interested in a hardware solution, I''ve used the MHZ19 CO2 sensor to great results. It''s an NDIR (read:not electrochemical) sensor with a UART interface. the processor unit. If not, read the 9 page or 10 page in manual. Wires with a battery in the handguard. 5 Programming method 1 × MHZ19 CO2 sensor Non dispersive aqspec ...
The MHZ19C module is a nextgeneration CO2 sensor based on the nondispersive infrared (NDIR) principle. MHZ19 C is the successor of the widely popular MHZ19 B. See below for a comparison. The MHZ19C 400~2000ppm CO2 sensor has builtin temperature compensation and communicates over UART and PWM with the host controller.
20201018· I’ve spent the last 2 days trying to make the code below work with an MHZ19B using a Wemos D1 Mini. The code I’ve found on the forum was from back in 2017 and believe to be for the MHZ19 not MHZ19B so after readapting it to make it work with Blynk, I’v...
