humidity – VoltLog

Jan 29, 2020· Welcome to a new Voltlog, you might remember these two sensors from a previous mailbag, this is the MH-Z19B and this is the CCS811 both of these report CO2 levels but they measure this differently and I’ll explain this in a moment. I got these two sensors in order to monitor CO2 levels in my home, to determine if the levels rise too much at night, especially during the winter time when we ...

MH-Z19B - RevSpace

Fake MH-Z19B (black PCB) (Added by Juerd 04:20, 30 November 2020 (CET)) 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)

MH-Z19 Carbon Dioxide Sensor - Leo's Notes

There is also a 'response time' interval of 2 minutes for the MH-Z19B which isn't specified anywhere in the datasheet and locks out the ability to do frequent polling for a CO2 measurement. This is mostly pointless since the PWM measurement is always constant, meaning the module measures the CO2 measurement constantly.

Experiences with an MH-Z19 CO2 sensor | Erland Lewin ...

My experiences with the MH-Z19 NDIR CO2 sensor Warning: I just destroyed my MH-Z19 sensor when soldering, I was changing connectors with lead free solder, iron set to 380 C. I had to heat for a little while to remove the old header. Now the sensor only gives a very low value, both on PWM and serial output. Before destroying the device, I was getting strange values around 900 ppm when I should ...
