More to the great development of electronic measurement technology. Digital signal has a good ability to resist interference and environmental interference material itself, so, now the analog signals of products on the market is gradually replaced by digital signal products, and the measurement products is more and more convenient. According to the survey of the market, although therere a lot about the environmental monitoring system tester on the market, but most is applied in the air, lakes, oceans, rivers, large detection systems, such as indoor small detection system about the detection of agricultural environment, but few on the market, therefore, to design a small simple and easy to use agricultural detection system for agriculture greenhouses to increase production, to avoid bad weather outside.
