[Abstract]:The temperature monitoring system in some key parts of the data center has the problem of unreasonable temperature setting. Therefore, a design scheme of wireless multi-point temperature real-time acquisition based on nRF24L01 is presented, and the hardware circuit and software implementation of the system are given. In the hardware circuit of the system, each temperature sensor corresponds to the I / O port of the single chip microcomputer, and the temperature sensor is identified by using the I / O port to improve the acquisition frequency. The software realizes the functions of temperature data transmission, display and archiving by compressing the data, reducing the transmission data, improving the wireless transmission efficiency and reducing the power consumption. The experimental results show that the system can collect multiple temperature points simultaneously with a frequency of 1 Hz. The error of acquisition temperature is less than 0.5 鈩，
