Title Greenhouse environment measurement system of wireless node (Hardware and software design )
Abstract
Comprehensive application of modern sensors, circuits and systems, intelligent control and wireless sensor network technology for greenhouse environment multi-parameter intelligent monitor and control system, completes the data acquisition and transmission unit design of the greenhouse environment temperature and humidity. This article focuses on the design of the sender of the wireless nodes,the system utilizes the microcontroller ATmega8 to control the temperature and humidity sensors SHT11, send measuring instructions, make it measure two parameters of the greenhouse temperature and humidity, to realize temperature and humidity data acquisition and data processing, after through the wireless transmission module will send data to the receiver, The receiver for data communication between the host computer.
The experimental studies show that the system can meet the current actual monitoring and control requirements of the greenhouse temperature, humidity concentration.
Keywords greenhouse wireless sensor node microcontroller ATmega8 SHT11
