Fake MHZ19B (black PCB) (Added by Juerd 04:20, 30 November 2020 (CET)) There are sensors out there, sold as MHZ19B, that seem to use the original firmware, but with different hardware. The hardware differs with the original MHZ19B in the following ways: Case: No circular bump over the lamp (a faint impression can be seen under an angle)
