Remote Monitoring in Agricultural Greenhouse Using Wireless Sensor and Short Message Service ( SMS )

— In traditional method of farming, human labors were required to visit the greenhouse at specific time and need to check the humidity level and temperature level manually. This conventional method is considered time consuming and needs a lot of work and effort. Therefore this research focuses on developing a system that can remotely monitor and predict changes of temperature level in agricultural greenhouse. The objective of the research is to develop a remote temperature monitoring system using wireless sensor and S hort Message S ervice (S MS) technology. The proposed system has a measurement which capable of detecting the level of temperature. This system also has a mechanism to alert farmers regarding the temperature changes in the greenhouse so that early precaution steps can be taken. In this research, several tests had been conducted in order to prove the viability of the system. Test results indicated that the reliability of the system in propagating information directly to the farmers could be gained excellently in various conditions. increases the value of resistance. But it not happens in capacitance behavior as firmness change. The capacitances were decreased as firmness improved. 1. INTRODUCTION The concern with a lot of consumer needs and demands for agriculture products has stimulated awareness for the farmer to increase their products in the market by implementing new technologies in this industry. Among the important things that may come to the farmers' interest is how to control the used o f natural sources and natural environment which agricultures depend on. Therefore, this problem has captured farmers' interest to implement agro-environmental remote monitoring method in their agriculture industries. The agro-environmental remote monitoring method can be implemented in various situations such as in monitoring qualities of soil and water. However this research focuses solely in remotely monitoring levels of temperature in greenhouse. By utilizing proper technology, the natural environment and resource, in this case is temperature, which is very important for the plants can be monitored efficiently. Previously, human labor plays a very important role in monitoring farm and plants in this industry. For some critical plants such as vegetables and flowers, they need 24 hours attention from human so that the quantities and qualities of the plant can be controlled. With proper management of collected data and information, this will provide them with strong foundation for future development and future growth of their plants. However, because of increasing size …
