Setting up the MH-Z14A CO2 sensor with Raspberry Pi ...

2020-05-17· So I bought an an MH-Z14A sensor to get CO2-levels at home, by attaching it to a Raspberry Pi 3. Indoor CO2-levels have pretty large impact on sleep and concentration. Usually measured in ppm (parts per million), the desired values are below 1000ppm. CO2 levels and effects source. PPM Effects; 250-400: normal outdoor air level: 400 - 1000: indoor, good airflow: 1000-2000: …

The last part is programming the Node-RED to decide what to do with the sensor data and send it to the cloud appropriately. LoRa node is set to show bytes by default, but if you are sending strings like the Hello World example, you can change to display UTF-8 encoded messaged. In case your Node-RED doesn’t have EVB-parsing code, you can import the following flow into Node-RED …

Co2 sensors : nodered

I have my rpi3 b+ running node red. After some learning, it is controlling the environment in my microgrowery with great success. Im controlling temp and humidity. I have DHT and DS18 sensors and relays. I would like to introduce co2 in to the mix. I see a lot of different co2 sensors out there. Are there some that work better with node red (a node-red-contrib)? Also the next step would be ...
