SI1143-M01-EVB 数据手册 - Silicon Labs（芯科）

Si1141/42/43 接近/环境光传感器模块The Silicon Labs Si1141/42/43 combines an active optical reflectance proximity detector with an ambient light sensor and an infrared LED into a single 10-Pin QFN package. Their dual port operation enables reliable proximity detection for moving as well as stationary objects. The Si1141 has 1 LED driver with an Integrated IR LED - RS 8920016. The Si1142 has 2 LED drivers with and integrated IR LED - RS 8920025. The Si1143 has 3 LED drivers with and integrated IR LED - RS 8920028. With the Si1143, locate three infrared LEDs in an L-shaped configuration to enable triangulation of an object and in turn, via host software, creating a gesture based user interface. These modules have photodiodes which can be used to measure both visible and infrared light. Detect levels as low as 6 lux.\- 可调接近检测，范围为 1 cm 至超过 50 cm \- 多达 3 个独立 LED 驱动器 \- 每个驱动器具有 15 种电流设置，范围为 5.6 mA 至 360 mA \- 25.6 μs LED 驱动器脉冲宽度 \- 高抗电磁干扰，不带屏蔽包装 \- 低功耗 ### 接近传感器### Microwave Motion Detector Modules, Microwave Solutions
