The BM32S2021-1 is an infrared proximity sensing module, which is designed for object detection applications. When an object enters the detection range, the reflected energy of the infrared will change. Proximity is determined by detecting changes in reflection. The product integrates active infrared emission, reception, and optical mechanisms. It features low power consumption, small size, long sensing distance (up to 100cm), and automatic learning of sensing distance.
The BM32S2021-1 can work in 2 modes. In I/O mode, when an object is detected, the LED on the module will light up, and the output pin will change from high to low. The default detection distance is set to 80cm in the factory, users can easily change the sensing distance. In UART mode, the external MCU can read and write various parameters through the UART interface, and quickly adjust module characteristics. In general usage cases, the I/O mode is sufficient.
