Abstract
Due to the problems existing in chicken house such as complex operating equipment for measuring environmental parameters,low efficiency of test,default indoor alarm system,a monitoring and alarm system of the house environment based on the Internet is designed.STM32 chip was used as the core,mainly functioning as a real-time monitor to supervise temperature and humidity of the chicken coop,carbon dioxide,ammonia,PM2.5,PM10,and when the temperature and humidity exceed the threshold value,interruption of power supply,phone or SMS alarm when fan is in default.Experimental results showed that the transmission distance of the henhouse was at around 11 m,packet loss rate being 0.2％.The relative error of temperature measured is 0.71％,and that for humidity is 1.91％.When temperature and humidity exceeded the threshold value,power supply was cut off,or fan was in default,the system would call the user or send SMS alarm,so that the user can real timely check the indoor environmental parameters through the Client.The experimental results show that the location of the test is positively correlated with CO2,and negatively correlated with ammonia.There is a significant positive correlation between the humidity and PM10,PM10 is positively correlated with PM2.5,and the temperature is negatively and significantly correlated with humidity.The environmental parameters of the chicken coop were measured at different locations and can reflect the overall environmental quality of the chicken coop.The system can continuously and accurately monitor the chicken coop environment,alarm in time,improve the management level of the chicken house,which has a broad prospect for livestock precision agriculture.关键词
