The invention provides a remote upgrade method of a sensor node based on a single-chip computer. The method comprises the steps that the communication connection between a server and the sensor node is established; whether or not the version number and the total number of packages of an updating application program transmitted by the server are received is detected by the sensor node; if yes, theversion number and the total number of packages of the updating application program are returned; after the version number and the total number of the packages of the updating application program arereceived by the server, an updating program is distributed package by package; an updated mark is set as 1 after the updating program is received by the sensor node, when it is detected by the sensornode that the updated mark is 1, the original application program is deleted, the updating program is read to perform updating, and the updated mark is set as 0. 本发明提供种基于单片机的传感器节点远程升级方法，包括：建立服务器与传感器节点的通信连接；传感器节点检测是否接收到服务器发送的更新应
