Automatic Temperature-Humidity Detector for Greenhouse
Abstract
To help mankind establish a good farmland ecosystem and promote the development of agriculture and rural areas, monitoring and control technologies have been used widely in agricultural production. On the basis of learning environment in a farmland ecosystem, a small-scale monitoring and control system for detecting data profoundly is referred here. The system is used for temperature, humidity control, the hardware part by the AT89C51, SHT11 as temperature and humidity-measuring the sensor, LED display module and other external microcontroller circuit composition of the relevant parameters. Part of a main program software, temperature and humidity data acquisition conversion subroutine, showing subroutine etc, C adopted procedures for the preparation, given the detailed software design methods.
Keywords: single chip; SHT11 temperature and humidity sensors; LED
