Introducing the NBSN95A - the latest Long Range NB-IoT Sensor Node from Dragino. Due to IC shortage, the NBSN95A is a substitute version of the Dragino NBSN95, with identical hardware performance and use of the same image.

The NBSN95A is designed for outdoor data logging and powered by an 8500mAh Li/SOCl2 battery, ensuring secure data transmission and long-term use. This device enables system integrators to quickly deploy NB-IoT sensor nodes for their IoT solutions, with easy programming, creation, and connectivity options.

Telemetry2U has a live demo of a Dragino NES01 soil moisture, EC and temperature sensor running on our IoT Platform.

NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology, which significantly improves the power consumption of user devices, system capacity, and spectrum efficiency, especially in deep coverage.

To use the NBSN95A, users need to check if there is NB-IoT coverage in their local area and if their local operator supports the bands that the NBSN95A uses. If the local operator supports it, the user can get an NB-IoT SIM card from the operator and install it into the NBSN95A to obtain NB-IoT network connectivity.

The NBSN95A is an open-source project based on the STM32L072CZT6 ultra-low-power ARM® Cortex®-M0+ microcontroller. Developers can obtain complete software and hardware design files, as well as adapters for their projects.

Experience the power and versatility of the NBSN95A today, and take your IoT solution to the next level with Dragino's advanced technology.
