overview

NBSN95 is a long-range NB-IoT sensor node. It is designed for outdoor data collection and is powered by a 8500mAh Li/SOCl2 battery for long-term use and secure data transmission. System integrators can use the NBSN95 to quickly deploy NB-IoT sensor nodes for their IoT solutions. The NBSN95 is easy to program, build and connect anywhere.

NarrowBand Internet of Things (NB-IoT) is a standards-based low-power wide-area (LPWA) technology designed to enable a wide range of new IoT devices and services. NB-IoT significantly improves user device power consumption, system capacity, and spectrum efficiency, especially in deep coverage areas.

To use NBSN95, the user must check if there is NB-IoT coverage in their area and which bands NBSN95 supports. If so, the user must purchase an NB-IoT SIM card from the local operator and install NBSN95 to obtain NB-IoT network connection.

NBSN95 is an open source project. It is based on the STM32L072CZT6 ultra-low-power ARM® Cortex®-M0+ microcontroller. Developers can obtain complete software and hardware design files and adapters for their projects.
