Hi all!
We have just launched a new firmware release, with many changes!
Find it here: Release v0.9.12 · fablabbcn/smartcitizen-kit-2x · GitHub
Most exciting changes are
-
You can now use a GPS and an OLED screen together. Before, it was not possible due to I2C bus issues.
-
We have added a new feature for noise measurements, on all versions: you can now detect peak frequencies on the noise spectrum. Previously, we were only reporting RMS levels, but as of 0.9.12, you can also report what is the highest frequency detected on the noise spectrum. In the example below, we would be reporting a peak frequency of 500Hz.
-
New sensors (both I2C): Sensirion SCD41 (for CO2 measurements - similar to SCD30 already implemented) and AMS AS7341 for color sensors, using a similar algorithm as the FFT on noise detection for detecting light flickering. The SCD41 is available as a grove module directly compatible with the SCK via the auxiliary port:
The color sensor is available at adafruit: Adafruit AS7341 10-Channel Light / Color Sensor Breakout [STEMMA QT / Qwiic] : Adafruit Industries, Unique & fun DIY electronics and kits with a Qwiic connector.
