Design of wirelessly charged temperature and humidity monitoring system for large-scale facilities

In a large-scale scientific facility experiment, it is crucial to monitor the temperature and humidity around the plexiglass when it is polymerized. The monitoring system is equipped with a lithium-ion battery, which is wirelessly recharged when the power is too low and can work continuously for 175 days in a fully charged state. Based on these, a wireless temperature and humidity monitoring system with wireless charging is designed in this paper. The system mainly includes a 433Mhz wireless communication module, a wireless charging module, and a temperature and humidity collection module. The temperature and humidity collection module collects the data and sends it to the host computer through the 433Mhz wireless communication module to realize real-time monitoring. After testing, the system can work normally in a fully charged state and ensure no data loss to meet the needs of large-scale scientific facility experiments.
