Abstract

In this paper, a 8-channel temperature and humidity acquisition system is realized adopting the technology of wireless communication and USB interface. And methods of multi-channel temperature and humidity acquisition as well as main characteristics and functions of the chip nRF2401 and CY7C68013A are introduced. The interface circuit which connects nRF2401 and MCU and the USB interface circuit are designed, also the procedure of the data acquisition and transmission is shown. With the advantages of flexible design, long communication distance, high transmission speed, the temperature and humidity acquisition system has good application prospects.
