MH-Z14 / MH-Z19 CO2 sensor - Let's Control It

2016-07-27· ESPEasy works fine even with the MH-Z19B version of the sensor, no problem here. I'd say this: - don't enable wifi, just test the sensor with a simple sketch without wifi (wifi won't consume power so powering the sensor will be more stable) - calibrate the sensor (leave it outdoors for 30 minutes and upload the sketch which does zero point calibration in setup() once or twice - if above does ...

MH-Z19B Range - Let's Control It

2019-11-25· Hello. I am using the MH-Z19B sensor with ESPeasy. I have a measuring range of 400-5000 PPM. Can I change the range to 400-2000 PPM in the ESPeasy interface? I connect via HW Serial0 GPIO-3 (D9) TX / GPIO-1 (D10) RX. Thanks. Top. TD-er Core team member Posts: 5162 Joined: 01 Sep 2017, 20:13 Location: the Netherlands.

MH-Z19 offset and scale differences!? - Let's Control It

2017-11-04· MH-Z19 always shows ppm in about 200 less then MH-Z19B. Even after few days in well ventilated room. Even after few days in well ventilated room. My plans currently (while waiting for S8) is to play with disabling ABC (with manual calibration) and again compare 4 sensors that I have ( I know that old MH-Z19 is crap).
