Traditional class attendance task is completed manually ,which appears many problems such as large amount of tasks ,low efficiency ,poor real-time performance ,system is designed based on ZigBee and GPRS network .The terminal nodes composed of RFID reading-w riting device and ZigBee communication module can control reading and w riting of electronic tag whose core is nRF24LE1 .Information of electronic tag is transferred from ZigBee-GPRS gateway to GPRS network ,and then is uploaded to the monitoring center according to the Internet network to come true remote monitoring and management of the class attendance task .The overall structure of system is introduced ,and the WSN's software and hardware design of each function nodes and the upper machine are given in this paper .The test of system shows that it can identify the information of electronic tag remotely ,and signal launch distance of electronic tag is about from 15 to 65 meters ,which is met requirement of system showing a good application prospect .
