Tech, Abha Gaikwad Patil College, Nagpur, Maharashtra, India ABSTRACT To analyze large amount of agriculture data computing environment to provide optimal solutions for effective farming. A decision tree is a diagram that a decision maker can create to help select the best of several alternative courses of action. The primary advantage of a decision tree is that it assigns exact values to the outcomes of different actions, thus minimizing the ambiguity of complicated decisions. Because they map out an applied, real- world logical process, decision trees are particularly important to build "smart" computer applications like expert systems. They are also used to help illustrate and assign monetary values to alternative courses of action that management may take. In this research, the use of a decision tree will process input parameter to alarm when an inputted parameter matches predefined conditions. Keywords: Decision Tree, Smart Computer, Sigsbee. I. INTRODUCTION A weather station is a facility with instruments and equipment to make observations of atmospheric conditions in order to provide information to make weather forecasts and to study the weather and climate. The measurements taken include barometric pressure, humidity, wind speed, wind direction, and precipitation amounts. Wind measurements are taken as free of other obstructions as possible, while humidity measurements are kept free from direct solar radiation, or insulation. Manual observations are taken at least once daily, while automated observations are taken at least once an hour. Investigation of ZigBee Wireless Sensors was to demonstrate the functionality and versatility of ZigBee (low power wireless networks) technology by way of implementing a fully functional. Wireless Weather Station within the EEE building for remote data logging application using two low power, ZigBee sensor nodes. ZigBee is targeted at applications that require a low data rate, long battery life, and secure networking. ZigBee has a defined rate of 250 kbit/s, best suited for periodic or intermittent data or a single signal transmission from a sensor or input device. Applications include wireless light switches, electrical meters with in-home-displays, traffic management systems, and other consumer and industrial equipment that requires short-range wireless transfer of data at relatively low rates. The technology defined by the ZigBee specification is intended to be simpler and less expensive than other WPANs, such as Bluetooth. II. EXPERIMENTAL SET ZigBee is a standard defines a set of communication protocols for low-data-rate short-range wireless networking. ZigBee-based wireless devices operate 2.4 GHz frequency bands. The maximum data rate is 250 K bits per second. ZigBee is mainly for battery-powered applications where low data rate, low cost, and long battery life are main requirements. 1) To transmit a single variable to a receiver unit which outputs a 4-20mA or 0-10V signal corresponding to the input. 2) To transmit multiple input values to a receiver unit which provides either multiple 4-20mA or 0-10V outputs or a single Ethernet or RS232
