I expected them then to give similar readings for CO2 ppm, but they didn't. Which means I might actually be able to fit it in a portable sensing platform, esp since it has on board humidity sensing. When activated for the first time a period of minimum 7 days is needed so that the algorithm can find its initial parameter set for ASC. images are CC BY 2.0. 461,28.6,12.5 473,28.5,13.0 We'll be installing 2 libraries. Sensirion recommends 7 days of continuous readings with at least 1 hour a day of 'fresh air' for self-calibration to complete. Too often, great ideas and memories are left in the digital realm, only to be forgotten. Note: The SCD30 has an automatic self-calibration routine. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current. 3. Temperature compensation corrects for internal heating; they differed by about 0.5 C. Setting the MBAR input to zero will deactivate the ambient pressure compensation. Downsides: Library compatibility is mostly Arduino-centric; originally was planning on using a Raspberry Pi but between drivers for other sensors and the clock stretching shenanigans the SCD30 pulls, using an Arduino dumping data over UART to the Pi wound up being easier.

The SCD30 is a high quality NDIR based CO sensor capable of detecting 400 to 10000ppm with an accuracy of (30ppm+3%). This allows us to visualize the current CO2 concentration and level color in green, yellow or red, depending if the CO2 level is good, bad or very bad. However, if you are looking for solutions to technical questions please see our Technical Assistance page. 3. UDOO Bricks are modules you can use to augment your UDOO boards and make them more versatile. To verify that everything is working fine, open the Serial Plotter, while your ESP32 ist still connected to your computer to see the sensor values measured by the SCD30 sensor: 2. The result is a plot that shows the course of CO2 in the room (in this case on my office desk). I did not have a alternate calibration source to test the sensor against which would have helped. Doubts on how to use Github?
