Fuente: Wipo "IOT" The utility model discloses an experimental device based on an NB-IoT communication technology. The system comprises an NB-IoT node, a sensor and a response module, the NB-IoT node comprises an NB-IoTterminal node used for NB-IoT protocol development and an NB-IoT development board used for being matched with a sensor and a response module for use. The sensor and response module is electrically connected with an NB-IoT development board used in cooperation with the sensor and response module. And the NB-IoT terminal node is used for NB-IoT protocol development, and the NB-IoT development board used in cooperation with the sensor and the response module is used for sending the data to the NB-IoT local server through the cloud server. Compared with the prior art, the NB-IoT communication technology experiment table meets the requirements of scientific research, meets the application requirements of teaching, is long in standby time, and is more suitable for experiments and practical training of the NB-IoT communication technology.
