| Abstract: | The multi-point temperature and humidity wireless monitoring system is pre sented based on the nRF9E5 CMOS chip. The hardware, software and communication protocol are designed according to the characteristic of wireless monitoring system. Anti-interference measures are utilized in both hardware and software to ensure communication reliability. The experiments results show that the system is reliable and expandable to monitor nodes. |
