    AI gases in low power mode or GAS_SCAN mode


    AI gases in low power mode or GAS_SCAN mode

    1 .Is it possible to get the values of the AI trained gases like H2S or field Sanitizer(GAS_ESTIMATE 1- 4) using the LOW POWER Mode or Ultra low power Mode.

    2 .I am attaching two documents one has the different modes and other has the sampling frequency of the gases. My final question is how I can get the values of all the parameters like temp, humidity, pressure, VOC, CO2 and the GAS_ESTIMATE(1-4) using the GAS_SCAN mode and what is the sampling frequency for the gases without using BSEC_HIGH_PERFORMANCE_SAMPLING as it consumes high current and will be used for testing purpose only mentioned in the data sheet(screenshot 2)?

    3. If I am using the frequency of 1/gas scan mode as mentioned in the screenshot 3 (1/10.8 as mentioned in gas scan mode in screenshot 2) but in the BSEC software I am getting Sample frequency is not supported with error code(-12). 

    Can anyone tell me how to solve these issues??

    Re: AI gases in low power mode or GAS_SCAN mode

    Hi Ayashkant123,

    1.Yes, the following sample rate were supported.
    #define BSEC_SAMPLE_RATE_ULP (0.0033333f) /*!< Sample rate in case of Ultra Low Power Mode */
    #define BSEC_SAMPLE_RATE_LP (0.33333f) /*!< Sample rate in case of Low Power Mode */
    #define BSEC_SAMPLE_RATE_ULP_MEASUREMENT_ON_DEMAND (0.0f) /*!< Input value used to trigger an extra measurment (ULP plus) */
    #define BSEC_SAMPLE_RATE_HIGH_PERFORMANCE (0.055556f) /*!< Sample rate in case of high performance */

    2.For BSEC2, sample rate of BSEC_SAMPLE_RATE_HIGH_PERFORMANCE is 0.055556 Hz.

    3.You could see it from BSEC2 software, current software only supported the sample rate in reply 1.
