Design of Lightweight, High Precision, Multi Scene Module Based on Narrowband Internet of Things

Le résumé fourni par la source

At present, the number of active IoT devices worldwide has exceeded 16 billion, but existing devices generally suffer from problems such as large size, short battery life, low level of intelligence, and poor stability. In response to the limitations of traditional IoT terminals in terms of size, power consumption, and scene adaptability, this paper designs a lightweight IoT intelligent module based on STM32 microcontroller and Narrowband IoT (NB IoT). Environmental data is collected through temperature and humidity sensors, as well as light sensors, and processed through the STM32 microcontroller. With the low-power, wide coverage, and strong link characteristics of narrowband IoT modules, remote data reporting is achieved. The experimental verification results show that the module has good performance and can accurately collect environmental data such as temperature and humidity. The module can be used in multiple scenarios such as bird tracking with good feedback.
