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

Apr 30, 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.

Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

Jul 11, 2017· Introduction: In this article we will do a simple functional test of the MH-Z19 CO 2 sensor by connecting it to a raspberry pi 3 UART and run a simple datalogger python program which prints results to the screen and stores results in a csv formatted file. The file can later be imported to matlab or excel for further analysis or just plot a graph of the collected data.

Feb 12, 2021· Presentation of the CO2 sensor MH-Z19. The MH-Z19 is a self-calibrated sensor, ie the measurement sent by the sensor does not require any mathematical treatment. In other words, the CO2 content expressed in ppm (parts per million) is recovered. The MH-Z19 has a PWM output and a UART digital interface (serial port).
