Publish the CO2 concentration of an MHZ19 sensor to ...

20210212· The MHZ19 is a selfcalibrated 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 MHZ19 has a PWM output and a UART digital interface (serial port). For this tutorial, we will already start by exploiting the PWM output. Measuring range: 0 – 5000ppm: Precision: ± ...

CO2/Humidity/Temperature Sensor Guillier

Between the screen, MHZ19 and the Wifi, it is probably around 200mA anyway. The USB port of the Wemos D1 mini is plugged directly on a small power adapter. The usb cable can also be used to upgrade the firmware as no OTA was implemented on this project. All in a "sensor box" Like almost everything else, directly from China, I found an enclosure designed for sensors (or thermostat?) which was ...

Measuring CO2 using MHZ19B and D1 mini pro Atomstar''s ...

// pin for uart reading define CO2_IN D0 // pin for pwm reading define MH_Z19_RX D2 define MH_Z19_TX D1. Once updated, compile and upload the program to the D1 mini and open the serial monitor (at the right baud rate) to read the CO2 values. Once everything is correct, you should see something like (in this case with debugging turned on): read CO2 uart >> Sending CO2 request. …

MHZ19 RevSpace

Here''s a teardown of the MHZ19 showing what it actually looks like inside. Basically a light source and curved mirror focusing the light onto a photo diode with an optical filter tuned to a CO2 peak. It has an STM32F103 processor inside, the same kind as the one on the famous ''blue pill'' board. Software. See this github repo for code using this sensor with an ESP8266 board (WeMos D1 mini).

20191222· The advantage is that you keep logging and uploading firmware over the serial (USB) port. When connecting the serial MHZ19B sensor to the ESP8266 board, you have two choices: Recommended: use software serial port (any pins, 12 and 13), lower baud rate, and keep logging. Use hardware UART (pins RX and TX) and disable logging, see also this ...
