(link to:) Sparkfun tutorial: Introduction
ESP32 IOT RedBoard from SparkFun
(link to:) Acconeer Github page
-----
- ordered the sparkfun module 2024-03-29.
- Range:
from the SparkFun tutorial:
"... water level measurements up to 20 meters with lens utilization, human presence detection up to 7 meters with lens-free utilization"
I have not yet found description of what "water level measurements" are, nor what "lens utilization" is ... - google search for "XM125 lens" found ref to "LH132 FOR XE124" ...
Digikey sells the LH132 lens kit for 34.63 Euro = $37.4
https://www.digikey.be/en/products/detail/acconeer-ab/LH132/13557003
Acconeer data sheet says lens is made from Polyamide PA12 (click "datasheet" in digikey link above)
Datasheet says most focused performance is obtained with Hyperbolic lens in "D2" holder position - Mouser product page says range 2m with 180deg view

"The lens is typically made out of plastic and can in many cases be incorporated in the cover of the plastic casing."
- Range:
- From SparkFun tutorial: (link above)
- this tutorial is written assuming you're using the SparkFun esp32 dev board (link above)
- Load the xm125 library:
Sketch --> Include Library --> Manage Libraries
search or scroll to SparkFun XM125 Arduino Library
click Install - Load the Sparkfun_Toolkit library:
[same procedure as xm125 library] - ??? also needed: ???
Acconeer XM125 A121 v1.5.0 (i.e. SDK for XM125)
i2c_presence_detector.bin
i2c_distance_detector.bin - STM32CubeProgrammer May be needed ???
See tutorial for detailed instructions... - For a given application, it may be necessary to flash new firmware into the XM125 module.
