INTRODUCTION 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. In traditional method we have to use more no of nodes to measure parameters from various part of the agricultural area. It increase total cost as well as it is somewhat time consuming case to collect the data from each node. 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 Measurement of NPK from soil ph. The proposed system has a measurement which capable of detecting the level of temperature, Element contents in soil (N,P,K), Humidity, Soil moisture Soil, Ph. 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 All rights Reserved

2 According to the past development [1] system based only for the surveillance system,but this system is now useful to both surveillance and the parameter measurement. Further one more system is designed [2] for only the parameter measurement which is not sufficient. Third system [4] is developed for the water level measurement in soil which is by using moisture sensor but this covers smaller area. Now which overcomes by using this system. Next to this [5] one system is comes which is helpful to measure potassium effectively but it is only up to potassium hence we have decided to include all the parameters. II. PROPOSED SYSTEM Following are the block diagram of transmitter, receiver end as well as overall block diagram of robot and user end which having ARM Controller at the center and motor control drives to manage the movements of robot through the agricultural land surface. All needful sensors are mounted on one arm which is placed properly on the robot. Whose motions are managed with help of program. Data can be share in between the robot and user end with help of RF Tran receiver. Video Camera is placed over the robot which is also movable according to need. At the receiver end system have CPU with graphical user interface and data storage provision. With the help of DC motors this robot is free to move anywhere in agricultural surface towards the required direction and then collect the amount of content of available parameters and simultaneously it will pick the real time video monitoring which is further useful to find the problems occurred in crops and other elements. Video monitoring is further useful to complete video monitoring, quality inspection. At the receiver end this system have GUI which is capable to display each parameter uniquely along with the real time video. User can manage the required movement from user side by using available provision from movement manager. One can manage the movement of robot towards right, left, forward and Backward. Figure 1.Block Diagram of Project This system required following sensors to measure the various parameters as 2.1 Humidity Measurement Humidity is one of the important parameter of any green house. As there are so many types of humidity sensors, here P-Hs-220 humidity sensor is used. The output of this humidity sensor is proportional to output voltage. At 20% relative humidity, the output is 660 mv, while at 90% relative humidity; the output is 2970 mv, i.e V. The output of the Humidity is connected to the ARM processor at pin no.35, which is the analog input (AD 1.2) of the ARM All rights Reserved 640

3 2.2 ph Measurement A ph measurement is actually, a precise voltmeter that measures the generated voltage of a ph electrodes.here Alpha ph 500 Transmitter with ph Electrode (EC100GTSO05B) The requirement of such measurement is an amplifier with high input impedance and has the gain of voltage-ph conversion. The standard ph probe is responsible to generate voltage of the range 59mV/pH.So a pre-amplifier is required with high input impedance input and with gain = 16.7 to give 1 Volt per ph. The schematic diagram of the ph measurement circuit is as shown below. 2.3 LM35 Temperature sensor LM35 Temperature sensor is the temperature sensor used to sense the temperature from field.it having Linear + 10 mv/ C Scale Factor,Calibrated Directly in Celsius (Centigrade),0.5 C Ensured Accuracy (at +25 C),Rated for Full 55 C to +150 C Range, Operates from 4 to 30 V NPK Microsensors(PHEC 04) The use of micro-sensors for in-field monitoring of environmental parameters is of great interest, particularly semiconductor-based micro-sensors. These sensors have many advantages over other sensors. The advantages includes smaller size, robustness, less output impedance, fast response.
