MH-Z19B - RevSpace

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 ...

Четыре датчика CO2 в одном устройстве: сверяем показания.

2019-09-06· А по цифре у mh-z19b элементарно отключается калибровка (либо включается тогда, когда нужно) Так что нет, по цене 2х mh-z19b я 1 t6703 не возьму. К тому же с паспортной точностью у него проблемы — он менее точен.
