CO2 meter using M5StickC -

2020-10-15· The CO2 sensor is MH-Z19B, NDIR type. Cause I’ve been working at home and being cooped up in my room, I decided to make a CO2 meter as a guide to ventilate my room. A MOX gas type that called CCS811 showed inappropriate results for measuring actual CO2 concentration, such as higher readings due to human farting, so I use a high-precision NDIR -type MH - Z19B in this case.

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

2020-04-30· 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 . And here is my sketch: const byte readCommand[] = …
