BM32S4021-1
2D IR Gesture Control Digital Module
General Information
The BM32S4021-1 is a 2D infrared gesture sensing module, which is designed for products with gesture detection function. When hands or objects enter the detection range, the reflected energy of the infrared will change. Gesture or object movement direction is determined by detecting changes in reflection between two infrared emitters and two infrared receiver tubes. This module supports detection at a distance from 1cm to 25cm.
The module provides a UART interface. The module parameters can be adjusted using the host. The module supports two modes: operating mode and sleep mode. In sleep mode, there are multiple detection cycles for users to configure to reduce power consumption, which can meet the application requirements of different power design products. This modular design has an advantage of implementing fast and convenient product development, which can be used to reduce product development period.
