We can get 13 units into Australia from SparkFun. If you order today, we can dispatch this stock between Nov 30, 2024 - Dec 02, 2024.
The SCD30 from Sensirion is a high quality NDIR based CO₂ sensor capable of detecting 400 to 10000ppm with an accuracy of ±(30ppm+3%). In order to improve accuracy the SCD30 has temperature and humidity sensing built-in, as well as commands to set the current altitude.
We’ve written an Arduino library to make reading the CO₂, humidity, and temperature very easy. It can be downloaded through the Arduino Library manager: search for ‘SparkFun SCD30’ or it can be downloaded here. We recommend using a Qwiic Breadboard Cable to connect the SCD30 to a Qwiic compatible board. The YeLLow wire goes in the SCL pin. The SCD30 also supports a serial interface but we haven’t worked with it.
The CO₂ sensor works very well and for additional accuracy the SCD30 accepts ambient pressure readings. We recommend using the SCD30 in conjunction with the Qwiic Pressure Sensor - MS5637 or the Qwiic Environmental Sensor - BME680 to obtain the current barometric pressure.
Note: The SCD30 has an automatic self-calibration routine. Sensirion recommends 7 days of continuous readings with at least 1 hour a day of ‘fresh air’ for self-calibration to complete.
We do not plan to regularly stock all SparkX products so get them while they’re hot!
