This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the Sensirion SENxx environmental sensor nodes
IMPORTANT: This software is meant to be used with the spin-standard-library (P8X32A) or p2-spin-standard-library (P2X8C4M64P). Please install the applicable library first before attempting to use this code, otherwise you will be missing several files required to build the project.
- SEN5x and SEN6x series (currently only SEN55 and SEN66 supported)
- I2C connection at up to 100kHz
- Read serial number, product number
- Read particulate matter, RH, temperature, VOC (index), NOx (index), CO2, HCHO (as applicable to the connected model)
- Measure all sensors, or RH&T, gases only (supported by SEN5x only)
- Manual fan cleaning mode
P1/SPIN1:
- spin-standard-library
- 1 extra core/cog for the PASM I2C engine (none if the bytecode-based I2C engine is used)
- sensor.temp.common.spinh (source: spin-standard-library)
- sensor.rh.common.spinh (source: spin-standard-library)
- sensor.co2.common.spinh (source: spin-standard-library)
P2/SPIN2:
- p2-spin-standard-library
- sensor.temp.common.spin2h (source: p2-spin-standard-library)
- sensor.rh.common.spin2h (source: p2-spin-standard-library)
- sensor.co2.common.spin2h (source: p2-spin-standard-library)

(other versions or toolchains not listed are not supported, and may or may not work)
- Tested with SEN55, SEN66 (using Adafruit SEN5x and SEN6x to QT/Qwiic adapter boards 5964 and 6331, respectively)
- Models other than SEN55, SEN66 not yet supported or tested
