Based on analyzing the communication module of a wireless monitoring system, this article designs the hardware and software with nRF24L01. Then it emphasizes on analyzing the question of anti-interference and low power consumption. Through researching the process of communication using the Petri net model, it adds the acknowledgement signal and changes the radio-frequency channel to respectively resolve the problem of interference from the system of frequency hopping spread spectrum and direct sequence spread spectrum. And it uses the mechanism of intermittent transmission to reduce power consumption. Through experimentation, the communication module is of small size, excellent anti-interference ability, low power consumption and high data rate. It is of high practical value and significant use for reference.
