Design of Agricultural Greenhouse Temperature and Humidity Measuring Instrument of Low Power Consumption
摘要
Abstract
The low-power temperature and humidity measuring instrument is designed , according to the actual need of agricultural greenhouse temperature and humidity control . MSP430 F427 connects temperature and humidity sensor SHT10 , collects the temperature and humidity inside the agricultural greenhouse , then displays the real-time measure-ment result on the LCD screen and stores the measurement result .The measuring instrument is Lithium battery-powered , it can work continuously and stably for six months or more by using a single fully charged Lithium battery , combined with the low-power sleep mode of MSP 430 F427 and timing off of sensor SHT 10 , while the solar charging function can be ex-tended to the system .The article shows the block diagram of the design and gives a detailed description of the tempera -ture and humidity acquisition circuit , USB interface communication circuit , segment LCD circuit , Lithium battery power supply circuit and the other hardware circuit design , and then gives system software program flow chart .Tests show that temperature and humidity measuring instrument can collect the temperature and humidity data inside the greenhouse accu -rately , provide an adequate basis for arranging agricultural production reasonably .关键词
