20191029· Available at low price (25) on AliExpress, it has a functional ABC (spanned over a week), decent accuracy (similar to MHZ19B) and power consumption nearly as low as the S8 LP. Its big advantage is the I2C interface, you don''t need a serial port like the S8 or MHZ19B. There is also a much more precise T6713 version but it''s 60.

20160727· Interesting info, I was wondering about the SenseAir S8 a bit because it seems to have a form factor and pinout identical to the MHZ19. The S8 is a more expensive though (like E75, for the S8 vs E25, for the MHZ19). I now guess this is because they developed a more advanced firmware inside the sensor, which for example does things like automatic background calibration algorithm. This may ...
