Holtek is pleased to announce the release of its new generation proximity sensing module, the BM32S2031-1. This new device includes fully integrated active IR emission, reception, and optical functions. When compared with the previous generation BM32S2022-1, this new module has a reduced size of 37% and retains its low power consumption and long sensing detect distance original characteristics. Having a modular design ensures much reduced product development time. These features combine to ensure that this proximity sensing module is suitable used for all types of smart home electronic products, such as smart door locks, smart makeup mirrors, smart sanitary ware and automatic dryers.
The module supports object detection with a distance of up to 100cm and has a low standby power consumption of 14μA at 3.3V, allowing the device to meet the requirements of a large number of product applications with different power designs. The module provides two user selectable output modes, namely I/O and UART types. When used together with a dedicated development platform, the required module characteristics can be rapidly setup and adjusted to implement fast and convenient product development.
With regard to pin connections, this new module has only four stamp holes, which can be increased by adding a pin header to implement connections at different angles, for example upright at 90 degrees. The high degree of flexibility offered by this module provides for a wide range of application possibilities. In addition to supplying a dedicated development platform, Holtek also provides a technical service team who can be called upon for assistance.
