Page 5: Distance Detection
2 Distance detection The goal of the distance detector is to produce highly accurate distance measurements while maintaining low power consumption by combining the features of the A121 sensor with powerful signal processing concepts, all wrapped with a simple to use API. -
Page 6: Thresholds
Ideally, the strength estimate is agnostic to the distance of the object. However, due to close range effects, the strength tends to be under estimated at short distances (< 1m). The strength is reported in dB. © 2024 by Acconeer AB - All rights reserved Page 6 of 13... -
Page 7: Peak Sorting
The detector recalibration carries out a subset of the calibration steps. All the calibration steps performed are agnostic to its surroundings and can be done at any time without considerations to the environment. © 2024 by Acconeer AB - All rights reserved Page 7 of 13... -
Page 8: Temperature Compensation (Recorded Threshold)
The purpose of visualizing them in the GUI is to guide in the process of determining the detector configuration, such as selection of threshold strategy and sensitivity. © 2024 by Acconeer AB - All rights reserved Page 8 of 13... -
Page 9: Api
The reason for this is that it is also dependent on the physical environment, as mentioned above. This means that close range leakage cancellation cannot be used in applications where the temperature changes more than 15 degrees Celsius during operation. © 2024 by Acconeer AB - All rights reserved Page 9 of 13... - Page 10 The implementation of calibration caching needs to be done in the application, i.e. it is not part of the RSS library itself. To see an example of how it can be done, please look in example_detector_distance_calibration_caching.c. © 2024 by Acconeer AB - All rights reserved Page 10 of 13...

Note that the heap is very dependent on the configuration. The configurations that have the largest impact on the memory are start_m, end_m, step_length and threshold_method. 3.4 Power Consumption The example application compiled from example_detector_distance_low_power_off.c on the XM125 module has an average current of 0.27 mA. © 2024 by Acconeer AB - All rights reserved Page 11 of 13... -
