摘　　要：为了解决无线模块发射距离近、穿透能力差的问题,将Si4432模块应用于普适农业系统[1],实现了较大范围农田的温湿度远程监测。该系统由控制中心和传感器节点组成,每个节点包括PIC16F877A单片机、Si4432无线模块和SHT10温湿度传感器,控制中心负责接收、显示、存储和发送温湿度信息。实验证明,该系统可以达到较远的通信距离和较强的穿墙能力,并且通信误码率低,具有很好的推广前景。A new design of Pervasive Agriculture System Based on Si4432 has been accomplished by Southwest University aimed to solve the problem of WSN（Wireless Sensor Network）,where the transmission distance is close and the force of penetration is week.The System include control center and sensor nodes,every sensor node is make up of PIC16F877A,Si4432 and SHT10.The control center is used to receive,show,store and send information.Test shows that the system transmit data distantly and strongly and the bit error rate are low,it can be widly used in WSN.
