The Design Of Environmental Information Query And Control System Based On GSM And Multi-sensors

The traditional environment or greenhouse information query should be by the artificial acquisition at the scene or through cable transmission of real-time data, but environmental monitoring position is complex and even lack of power supply, transmit data with cable connection cost too much.The efficiency of artificial observation and data record is low and not convenient. The monitoring methods of these equipments to gain environmental information(sensor types) cannot be customized by user’s requirements, or to gain specific environmental information in a small scale.The device sold on the market of wireless monitoring is very large and expensive, and it cannot be moved.What’s more,it is lack function of remote control.Power supply for the design of environmental information query and control system based on GSM and multi-sensors is solar energy. So,it is green, flexible and mobile. The environmental information about atmosphere or the greenhouse,such as temperature, humidity, light, pressure, CO2 concentration, not only display on the LCD panel locally, it also can query by instructions of mobile phone, the message received include multiple environmental information, it can send an alarm message to user when environmental information overrun.When a user journey, it can send a message instruction to open the water valve actuator for irrigation, etc. Firstly,this system can query multi-sensors of environment information integratedly in real-time, to judge the atmosphere or the state of greenhouse environment, and control and optimize the environment of the adverse factors remotely.This system can provide accurate environment information to users remote and control function at low cost, offer users functions of unattended monitor and control.
