Design of the Monitoring System for Temperature ,Humidity and Harmful Gases in Laboratory
DING Tao,LIU Xiangji
(School of Chemistry &Chemical Engineering,Yan an University,Yan an 716000,China)Abstract :With the rapid development of science and technology,the requirement for environment is higher and higher in modern laboratory,for example,temperature and humidity,by which the accuracy of experimental data and the normal operation of laboratory equipment may be affected.However,the traditional temperature and humidity monitoring system adopts the desktop as a general monitoring terminal,and requests specific place and dedicated network under the condition of equipment support ability to monitor the target environment.This greatly limits the application range and flexibility of the monitoring system.With above as the background,the hardware and software of a wireless monitoring system of temperature,humidity and harmful gases in lab have been designed.In this system,ESP8266is used as the main control chip and DHT21compound sensor is for temperature and humidity collection.The functions of system include the real-time measurement of temperature and humidity,Android application(APP)remote monitoring and historical data query,etc.The test results show that the system is simple to use,offers accurate data and stable operation.This system can realize wireless remote and real-time monitoring in the field,which improves the application scope and flexibility of the monitoring system.The wireless monitoring technology has reference significance for the monitoring for growth of agricultural products,pollution in environmental protection,and intelligent household remote control in the future.
