NBSN95 是一个远程 NB-IoT 传感器节点。它专为户外数据记录而设计,由8500mAh Li/SOCl2 电池供电,可实现长期使用和安全数据传输。系统集成商可以使用 NBSN95 为其物联网解决方案快速部署 NB-IoT 传感器节点。NBSN95 易于编程、创建和连接无处不在的事物。
NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage.
To use NBSN95, user needs to check if there is NB-IoT coverage in local area and with the bands NBSN95 supports. If the local operate support it, user needs to get a NB-IoT SIM card from local operator and install NBSN95 to get NB-IoT network connection.
NBSN95 is an open source project. It is based on the STM32L072CZT6 ultra-low-power ARM® Cortex®-M0+ micro controller. Developers can get completely software and hardware design files and adapter for their projects.
