Abstract
Aiming at the importance attached to the indoor environment, design and development of the indoor environment monitoring system based on NB-IOT and sensor technology. The real-time system by a plurality of sensor nodes collect indoor environment parameters, ZigBee embedded transmitted over the network to the gateway, and then use the NB-IoT uploaded to the service center stores the data; APP monitoring indoor environment using a mobile phone. Users can view the indoor environment in real time and historical data track through remote terminals. Experiments show that the system can achieve real-time monitoring of the indoor environment. The system is stable, low-cost, low-power, easy to operate to meet the design requirements.
