1 Green Huse Mnitring and Cntrlling Using Andrid Mbile App Ullas S Patel 1, Saiprasad 2, Shravankumar 3, Veerabhadra K J 4 Dept. f ECE, The Oxfrd Cllage Of Engineering, Bengaluru, Karnataka, India Abstract- Smart Green Huse andrid app is develped t Mnitring and cntrling the micrclimatic envirnment inside a green huse.frm the green huse easly get sil miseture,humidity and temperature sensr value t andrid app,accrding t sensrs values and we set predefined threshuld values fr each sensr,depending n sensr readings we are ging t cntling using water sprayer,cling fan,rftp and fcus light and just press the buttn in andrid app we can cntrl make n/ff mtrs and it als has datasheet f all Hrticulture plantatin and seasn wise precatin material fr mnitrning and cntrlling.the bjective f this prject is t design a simple, easy t install, user frendily t mnitr and recrd the values f temperature, humidity, sil misture and sunlight f the natural envirnment that are cntinuusly mdified and cntrlled in rder ptimize them t achieve maximum plant grwth and yield. The result shws that the cnditin specified in sensr s datasheet and system in reality is apprpriate. The achieved test result cncludes that the system is wrking prperly. Keywrd: green huse, micrcntrller- 8051, wireless netwrk, sensrs,drivers,andrid phne. I. INTRODUCTION Green huse farmers cannt precisely detect level f level f humidity inside the green huse. They nly knw the cnditin inside the green huse manually and by feel it by themselves. Ultimately, experiences play a bigger part n their daily peratins. If the cnditin is t dry, they will give water t the plants r sil, but if it is t humid, they will pen the rftp f the green huse, especially in the daylight. In designing this device, there is limitatin t prblems, t see hw far this system can d its tasks. This limitatin accrding t the situatin where this system will be used later. There are 3 kinds f activity that are designed in the system. First, mnitr the humidity level in the green huse. Secndly, if the green huse is t dry, the water sprayer can be activated, t increase the humidity level. It als can deactivated water sprayer. Third, if the green huse is t humid, the rftp can be pened t lwer the humidity level. The third functin can be use t pen r clse the rftp based n the needs. This embedded system fr mnitring and cntrlling the green huse is based n measuring the humidity and temperature by sensr that lcated at different places. The mnitring and cntrlling is cnducted thrugh Andrid Smartphne. The prpsed system is an embedded system which will clsely mnitr and cntrl the micrclimatic parameters f a greenhuse n a regular basis rund the clck fr cultivatin f crps r specific plant species which culd maximize their prductin ver the whle crp grwth seasn and t eliminate the difficulties invlved in the system by reducing human interventin t the best pssible extent., The sensrs sense the change and the micrcntrller reads this frm the data at its input prts after being cnverted t a digital frm by the ADC. The micrcntrller then perfrms the needed actins by emplying relays until the strayed-ut parameter has been brught back t its ptimum level. Since a micrcntrller is used as the heart f the system, it makes the set-up lw- Page 710

Thus, this system eliminates the drawbacks f the existing set-ups and is designed as an easy t maintain, flexible and lw cst slutin.

Lng term expsures t cnditins utside nrmal range, especially at humidity >80%RH. After return t nrmal range it will slwly return twards calibratin state by itself. Prlnged expsure t extreme cnditins may accelerate ageing. [5] Figure 10. Operating Cnditin f SHT 11 Sensr [5] In testing f wrk characteristic sensr, it used heat frm GPU cre f a cmputer thrugh GPU ventilatin t increase the temperature inenvirnment. This test used a clsed bx t put the cmputer and sensr. Figure 8. Mnitring System Figure 9 shwn the picture f Cntrlling System in Andrid Mbile Phne. Figure 11 shws the graphic f sensr wrking characteristic in this system (shwn in red) cmpared t ideal sensr characteristic (shwn in blue), where the cmparisn between temperature and humidity is in nrmal range SHT 11 sensr. In the red line, the tests are frm 30C until 70C. In cnclusin, sensr wrks fine and fit with the value in datasheet. The system shws that the sensr wrks prperly. Figure 11.

5 VII. CONCLUSION The system is successfully built and run in reality based n Technlgy Acceptance Mdeling. The utput fr the given analg input values are visualized in andrid applicatin system. The analg value given by the sensr changes it int a digital value. The andrid sftware is already wrking prperly and apprpriate with the purpse in the beginning, that is t get humidity value frm green huse and give input t cntrl cmpnents in green huse. After develpment is finished, test fr sensr s wrk is dne and device is wrking prperly. The testing that has dne shws that cnditin in datasheet f sensr and in system is apprpriate. The test result shws in temperature 30 C t 70 C, humidity is still in nrmal range area. If temperature gets higher and mre, relative humidity will be decrease and ges near t zer. [4] S.U.
