摘　　要：当前,市面上的距离感应器多种多样,例如超声波雷达、红外线感应以及位移式距离传感器,这些传感器或多或少都存在一些缺点。文章致力于研究基于生活中比较常见的、成本造价较低的WiFi模块所组成的无线距离感应器,利用普通WiFi模块发射出WiFi热点,从而通过另一块WiFi模块去检测热点的RSSI信号强度判断出两个WiFi模块的距离远近。At present, there are various distance sensors on the market, such as ultrasonic radar, infrared sensing and displacement distance sensors, which have more or less disadvantages.This paper is devoted to studying the wireless distance sensors based on the relatively common cost WiFi modules in life, and uses the ordinary WiFi modules to emit WiFi hot spots to determine the distance of the two WiFi modules to detect the RSSI signal intensity of another WiFi modules.

关 键 词：WIFI RSSI 距离感应
