Design of monitoring environmental factors of endangered plant Paphiopedilum armeniacum

Objective]The present research was conducted to understand the real-time environmental parameters of Paphiopedilum armeniacum and to master its optimal living environment in order to provide references for further environmental parameters control,species growth promotion and propagation,species extinction prevention,and ecological environment protection.Method]Using AT89C51 as the microcontroller,parameters such as temperature,humidity,and light intensity of the living environment were monitored and the data were collected by DS18B20 temperature sensor,HS1101 humidity sensor,TSL235 light-frequency converter,respectively,and then the data were wirelessly transmitted by PTR2000 module.Result]AT89C51 singlechip could jointly monitor temperature,humidity,light intensity,and other environmental factors;the corresponding values of environmental factors were displayed on nixie tube with the transmission distance of 300 meters.Conclusion]This research design is suitable for monitoring environmental factors of Fugong,Bijiang,and Lushui regions of Yunnan Province,where Paphiopedilum armeniacum are grown.Environmental factors measurements,such as outdoor joint monitoring and wireless transmission,could be understood based on the sensors adaptability to local environment,reasonable data collection,and different transmission modes.
