Take spectrometer readings (between OD readings) from the Adafruit AS7341 attached to your Pioreactor
Project description
Spectrometer reading plugin
Records spectrometer readings from the Adafruit AS7341 spectrometer sensor attached to your Pioreactor.
Available wavelengths:
415nm
445nm
480nm
515nm
555nm
590nm
630nm
680nm
This plugin also installs a SQL table, as7341_spectrum_readings
, that will store the readings.
How it works
In between optical density recordings, the white-light LED on the AS7341 board turns on. The light is reflected back towards the board, with some wavelengths being absorbed by the culture. All sensors for each wavelength are recorded. The LED is turned off.
Each wavelength is sent to MQTT under the topics:
pioreactor/<unit>/<experiment>/spectrometer_reading/band_<xxx>
And it is also placed in the SQL table as7341_spectrum_readings
.
