2021-05-06· Anyone with a MH-Z14? eXistenZ February 23, 2016, 5:23pm #1. My MH-Z14 CO2 sensor seems unreliable. Does anyone have any experience with these things? The PWM output is easy to convert to ppm, but the dutycycle stays the same, more or less. Am I the first person to be ripped off by the chinese selling me cheap junk?
2017-04-07· The MH-14 uses SC16IS7XX i2C Slave SPI interface. The SC16IS is a slave i2C SPI interface to a single channel HIGH performance UART, it offers data rates up to 5 Mbit/s running at low power with sleeping current and also provide the application with 8 programmable IO pins. The SC16I enables seamless protocol conversion from i2C us or SPI, and RS232 or RS485 and fully bidirectional …

2021-06-17· I have a project, that among other things measures CO2 levels using this arduino mega 2560 R3 and an MH-Z14a. I've attempted calibrating the sensor by letting it run outdoors for >24hours and also by sending the zero point calibration command after 30min. Neither seem to work as I still read below 400ppm (between 140 and 200ppm) outdoors. Here's a "working" slice of the code that I'm hav...
