MH-Z19 with Arduino null output. Ask Question Asked 4 years, 1 month ago. Active 4 years ago. Viewed 829 times 0 I want to get CO2 value by using MH-Z19. I tried this code with Arduino uno R3 but I always get this result (CRC 0/0). I didn't understand where is the problem. I linked A0 with TX of sensor and A1 with RX, I powered the card with /Vin to visualize the result on PC via USB port. ...

arduino - MH-Z19 CO2 sensor giving diferent values using UART …

09/10/2016· I have a MH-Z19 CO2 sensor, according the data-sheet I can obtain PPM values via UART and PWM. The difference between both method is the limit in the CO2 concentration, where UART I should have readings between 0-5000ppm, and via PWM I should have readings between 0-2000ppm. I just wanted to know if I can have the same readings using both methods, but after tried I'm realized …

10/06/2019· 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. Higher levels lead to various negative effects like a feeling of “bad air” and so on. The concentration of 2000 - …
