NodeMCU v2 with MH-Z19B CO2 sensor UART read problem ...

30/04/2020· 1. I'm trying to read data from MH-Z19B sensor to NodeMCU v2 board with a simple circuit like this. Some key points, which could be not that obvious from picture: - sensor has separate power supply of 4 AAs, providing ~5,5V. - sensor's TX connected to GPIO15 (TX D2) of NodeMCU. - sensor's RX connected to GPIO13 (RX D2) of NodeMCU.

MH-Z19 CO2 sensor | MySensors Forum

23/03/2017· I have to mention I'm using the MH-Z19B, and powering it with 5V, as opposed to the of the arduino. I also tried with the mhz19_uart lib, but didn't go further with it as the samples where not working out of the box with the z19B. Will probably give it another try, though...

AQC-0-0-0-0 - RevSpace

The AQC-0-0-0-0 is a CO2 sensor, much like the MH-Z19B. We have no idea who makes these and where they can be bought, but it's an aesthetically pleasing device that seems to work at least as well as the famous MH-Z19B. It has the same form factor and is pin compatible. Regarding the protocol it is only (somewhat) compatible with the MH-Z19 for the commands 0x86 and 0x87. The sensor ...
