In the field of agriculture, use of proper method of irrigation is very important from yield point of view and scarcity of water. Traditional drip irrigation is a method of applying water and fertilizer near the root zone of the crop to minimize low humidity stress within the root zone in the soil. However, being a manual system that works under low or medium pressure, unmeasured quantity of water is given to the crop. Sometimes excessive amount of water is continuously given to the crop or sometimes very less amount of water is given to the crop, defeating the purpose of the system [2]. In this, Low humidity stress has significant effect on the plant growth, crop response, and timing of maturity, quality and yield of product. This system makes use of Humidity sensor, Temperature sensor are used. O/p of these sensors is given to the A/D converter, which converts it into digital domain and then fed to the controller for the further process. The software of the system consists of data acquisition, calibration, displaying information and taking decision. The developed system has numerous advantages such as automation, user-friendly measurement and upgrading of the design is possible. Moreover the system is portable, field usable, reprogrammable, and can be used at any geographic positions and weather conditions. In the conventional drip system, quantity of water applied to the plants depends on various parameters such as type of soil, rate of evaporation, type of crop and atmospheric conditions etc. Using some standards based on day to day experience, water requirement of crop per day is calculated. Water required for the crop is supplied by keeping motor ON for a particular period. Thus farmer has to follow the irrigation timetable meticulously and some supervisor needs to be present there for whole day, it is always the possibility that more water may be given to the crop or in some cases lesser amount of water may be given, which may affect the yield [1].
