Automatic learning of sensing distance
HOW TO LEARN THE SENSING DISTANCE
The BM32S3021-1’s sensing distance is 5 to 25cm, and it is configurable. Steps for learning distance:
To change the infrared detection position, place something, such as a sheet of paper, above the infrared sensor of the BM32S3021-1.
For example, if you want to change the distance to 10cm, place something above the infrared sensor from a height of 10cm.
Issue the command to the BM32S3021-1 to enter the distance learning mode. The INT pin output low under distance learning mode.
The INT pin output high once the distance learning completed.
