One Esp32 for 2 sensors? - LEDgardener

07/08/2021· I now also want to run a MH-Z19 sensor to monitor Co2. Can I add the MH-Z19 code from the esphome helper code site to the same esp32 and run both the MH-Z19 and ruuvi on it? or do I need 2 separate esp32's? Thanks, Jeff.

MHZ19 - RevSpace

The sensor works as intended, some software has been written to read the CO2 level and publish measurements it on MQTT. It is also clear how to change the measurement range from 0-2000ppm to 0-5000ppm in software. Currently, it's running in Space3, publishing its value on a topic on MQTT, you can read this as follows: mosquitto_sub -h -t revspace/sensors/co2/# -v See also https ...

22/12/2019· Ik heb een aantal van die BME 280 sensoren naast elkaar aan 1 ESP32 Gehad om hun gedrag te bekijken. Ik kwam er achter dat ze temperatuur veranderingen goed aangeven, maar bij elke keer opnieuw opstarten hadden ze een nieuwe offset. Die offset kreeg ik niet weggewerkt. Voor CO2 was ik nog aan het rondkijken. De MHZ19B ziet er interessant uit.

MH-Z14 and MH-Z19 CO2 Sensors • Wolles Elektronikkiste

12/06/2021· In my experiments with the MH-Zxx CO2 sensors, I found that they responded more slowly than the Technoline WL 1030. Perhaps this is simply design related, and it takes longer for the CO2 to penetrate the MH-Zxx sensors. There may also be a damping algorithm running in the background. In any case, the effect is that the measured values of the MH ...

MH-Z19 0-5000PPM Infrared CO2 Sensor For CO2 Indoor Air ...

The MH-Z19 is an indoor CO2 sensor. It is just a sensor, which means that you need to have separate system to read and control the data measured by the MH-Z19. This can for example be a wemos or nodemcu device that you need to have in place to control the MH-Z19 sensor. When you have this setup in place, you are able to send data from this sensor to your home automation or smart home platform.
