Its principle is to use physical effect and chemical effect, biological effect, the physical quantity, the measured chemical quantity, biomass and other parameters is converted into electricity. Sensor technology is one of the most important basic technologies of modern information technologies; many countries take the sensor technology as cutting-edge technology. With the development of modern detection, control and automation technology, sensor technology has been paid more and more attention, especially with the needs of science and technology, economic development, application of sensors in various fields in the increasingly obvious. Modern agriculture is to replace the traditional agriculture to the modern science, technology and equipment of armed, socialization, commercialization of agriculture and modern management methods to manage, is the modern industry has strong competitiveness in the national economy. Each link in modern agriculture, sensor technology has been widely applied. Keywords: Agricultural sensors; research status; development trend 第一章 引言 传感器是指那些对被测对象的某一确定的信息（如温度、压力、湿度等）具有感受与检出功能, 并按照一定规律转换成与之对应的有用电信号的元器件或装置。有时, 传感器感受到的信号是一些微弱的信号,干扰信号有时幅度可能会超过需检测的信号, 因此消除
