Combining characteristics of the greenhouse and the problems existing in the process of environment parameter measurement, an environment parameter intelligent measurement system based on GPRS has been put forward and the hardware circuit and the software design of the system have been completed. The system is mainly composed of a parameter measuring terminal, GPRS network and a monitoring host. The parameter measuring terminal with the core of single chip microcomputer can obtain environment parameters on the scene through a high precision sensor, and then, it sends the data through the GPRS module based on wireless network to the monitoring center, and the monitoring host will receive data that will be real-time displayed. The system has the characteristics of good expansibility, low cost and high accuracy so that it can meet the requirements of wireless acquisition of remote data and has broad prospects of application and a good promotional value.
