BSEC library has been updated - Need update for catena4460_bsec_ulp.ino #69

Closed dhineshkumarmcci closed 5 years ago

dhineshkumarmcci commented 5 years ago

Bosch has updated the library for BSEC and the latest version is v1.4.7.2.

Sketch catena4460_bsec_ulp.ino has been written based on BSEC software v1.4.6.0, so the sketch has to be updated to work with BSEC v1.4.7.2. Please find the code part need to be updated below:

https://github.com/mcci-catena/Catena-Sketches/blob/01c3a841b3f9fbc82fcdded2f0023268bac770f3/catena4460_bsec_ulp/catena4460_bsec_ulp.ino#L318-L327

Here in the sensor list, Bosch have changed output (virtual) sensor BSEC_OUTPUT_IAQ_ESTIMATE to BSEC_OUTPUT_IAQ in their library bsec_datatypes.h under "BSEC_1.4.7.2_Generic_Release_20190122\Arduino\BSEC\src\inc\". Also they have added three other output (virtual) sensors in their library:

BSEC_OUTPUT_STATIC_IAQ = 2,                             /*!< Unscaled indoor-air-quality estimate */ 
BSEC_OUTPUT_CO2_EQUIVALENT = 3,                         /*!< co2 equivalent estimate [ppm] */   
BSEC_OUTPUT_BREATH_VOC_EQUIVALENT = 4,                  /*!< breath VOC concentration estimate [ppm] */

@terrillmoore We have modified the catena4460_bsec_ulp.ino to work with the latest version of BSEC library v1.4.7.3. We see that the library has been written to support data either in int or float by handling BME680_FLOAT_POINT_COMPENSATION macro as per user's requirement.

As we calculate data as a float value, we have to un-comment BME680_FLOAT_POINT_COMPENSATION and it is added as a step in README.md.

With the long run, we see the IAQ accuracy remains to be '1' always. For your reference, we have added the log of few transmissions below:
