Title Data acquisition unit of environmental sensor
Abstract With the development of wireless sensor technology, its application scope has deep into the life. And it also has a broad application prospect. Especially in the aspect of environmental monitoring, with the help of the sensor network regulation of greenhouse unmanned monitoring system has been realized. There are many sensor networks node way of data collection, but every way has its own disadvantages. This paper introduces these methods and compares their advantages and disadvantages And this paper introduces the sensor’s network architecture and technical characteristics and requirements. With these sensors connected to the chip finally made a simple and easy environment monitoring sensor, and measure the environment with the sensor.
