There are sensors out there, sold as MH-Z19B, that seem to use the original firmware, but with different hardware. The hardware differs with the original MH-Z19B in the following ways: Case: No circular bump over the lamp (a faint impression can be seen under an angle) No raised edges around the square "windows" Slightly more yellowish gold color; PCB: Black instead of green. This is the most ...
