Capteur CO2 MH-Z19B Arduino

Carbon Dioxide Sensor MH-Z19b - Part 2 - Software | …

27-05-2020 · There is a nice library for the MH-Z19b sensors for the Arduino framework. To use it in the project update platformio.ini file in the root of the project. lib_deps = MHZ19. The sketch for testing the sensor and displaying the CO2 concentration in the serial console is very simple. As the hardware UART is already occupied by programmer and ...

NodeMCU v2 with MH-Z19B CO2 sensor UART read …

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.

Comparison of CO2 sensors MH-Z19B and CCS811 | …

10-06-2020 · Both sensors are designed to measure the level of carbon dioxide indoors. The CCS811 sensor has many advantages over MH-Z19B - significantly smaller size, lover voltage and current, lower price.. For comparison, both sensors were connected to ESP8266 development boards with very similar firmware. Readings were collected every 10 seconds and sent by MQTT protocol to a Raspberry PI …
