MH-Z19B STM32

IRSend RAW Encoding - Tasmota

There are 18 bits (Burst pairs) in this code. Next pulses are measured in pulses of the IR clock, so it depends on the frequency. With 36KHz, each pulse is (1000/36) microseconds So you need to multiply by for Tasmota to get actual µs 000F 000A - becomes 415,277 0006 000A - becomes 166,277 And so on...

DIY and electronics Archives | The blog of a gypsy engineer

Measuring CO2 with MH-Z19B on ESP32 with MicroPython. In the previous posts, I described a simple weather station that measures temperature and humidity and sends the measurements to a Google sheet. The system is supposed to be used at home. Therefore, one of the next possible improvements can be measuring air quality in a room. That can be done, for example, by adding an MH-Z19B …
