It is an oxidation procedure where tea leaves change shading and smell. Humidity and temperature are two vital physical parameters which assume a pivotal part in delivering great quality tea. This work is an endeavour to create and actualize a checking framework for aging room of tea production line. Because of the bigger measurement of the maturation room, it requires a few quantities of observing point for assessing normal condition. Sensor hub at each checking point is associated by means of RS 485 system which works with a convention created for this reason. Every sensor hub comprises of sensors, flag molding, controller and RS485 handset. If the temperature and humidity is above the limit it will send the notification to mobile through IOT.

2 I.INTRODUCTION Tea is a major agricultural and export item of Assam and it plays an important role to the economic growth of India in general and Assam in particular. Almost 2500 numbers of tea gardens are there in Assam producing almost 51 % of total tea production of India. But the proper monitoring and control of different tea process parameters like temperature, relative humidity, moisture content at different level is done by manual means and guesswork. In rare cases where modern measurement methods are implemented, but due to lack of proper expertise in operation and maintenance they are not effectively utilized. As a result the quality of product and efficiency of operation suffer badly, affecting the performance of the industry. Black tea processing is performed through a few sequential operations: plucking, withering, rolling, oxidation, drying are mentioned in below (fig1) Figure(1): Cycles of tea processing stages Among every one of these procedures maturation is a standout amongst the most critical process where tea leaves change shading and smell. It is a perplexing chain of biochemical responses those happen amid the aging procedure and once such changes achieve their ideal point, the procedure ought to be halted (4). The physical parameters that influence the aging procedure are I) Relative Stickiness ii) Temperature. In this way control of these physical parameters will be extremely valuable to keep up legitimate aging condition to have wanted nature of tea (5).In this investigation they have explored different avenues regarding electronic nose based framework in 81 maturation cycle and by utilizing diverse measurable apparatuses, they can associate the electronic nose based outcomes with colorimetric test and in addition human board test to discover the ideal aging time. Bhattacharya et al. [6] utilized electronic nose based procedure to screen the maturation procedure of dark tea and effectively associated these information with the aftereffects of colorimetric tests and human master assessment. Tudu et.al. [7] contemplated distinctive enhancement method for dark tea order by utilizing electronic nose which includes a gas sensor cluster 397

3 II.WITHERING The minute a tea leaf is culled from the tea plant, it starts to shrivel normally, a procedure we call wilting. Be that as it may, once the tea leaves achieve the preparing office; this procedure is controlled by the tea maker. The reason for a controlled wilt is to set up the leaves for additionally preparing by lessening their dampness content and to take into consideration the improvement of smell and flavour mixes in the clears out. Controlling the shrivelling procedure implies nearly observing dampness, temperature and wind stream after some time. III.EXISTING PROJECT Withering is the first stage of the tea processing. Here the temperature and the humidity are important for this process. In the existing project they were used PIC microcontroller for the project, LM35D temperature used separately and relative humidity low power RH to voltage converter (HIH 4000) is used. In this project the database are recorded. The procured information indicates ±8% variety from the normal if there should arise an occurrence of Relative Humidity and ±2.5 ºC variety if there should arise an occurrence of temperature for a specific day of the aging room of the tea manufacturing plant amid tea creation. It only shows the graphical representation of the temperature and humidity. IV.PROPOSED PROJECT In withering the tea leaves are can be either put under sun or either cool in breezy room to full moisture out from the leaves. This process is also one of the stages of tea processing. We use the two sensors for sensing the temperature and humidity. In this project we use TI CC3200 module which is mainly prepared for IOT connection. In this module temperature sensor is interconnected and humidity sensor is going to add. This module is acts as a microcontroller. The description of this module is in below figure (fig2). It will place in the withering process area. Then the temperature sensor senses the reading and if the reading is above the tea leaves will become waste. If the temperature is high is automatically detect and send message to the manager or who is working in that area using IOT.The temperature sensors description is in the figure(fig3). The humidity sensor will also do this process it will detect the leaves moisture content and if it is high it send message to a worker. The humidity sensor description is in the below figure (fig4). We are developed a relative humidity and temperature measurement instrument with builtin sensing circuitry.it has a low cast where an ease RH and temperature observing framework is concocted utilizing two indistinguishable thermistor and its execution was considered by recreation. Be that as it may, organizing capacity isn't consolidated with these frameworks and need singular focal checking and information logging framework. As the maturation room is bigger in measurement, so arrange based framework is the earlier requirement for checking these parameters at the same time with a focal observing framework. So an instrument with on line focal observing and information logging highlight having organizing capacity for Aging procedure is relied upon to be useful for controlling these parameters and in this way quality change. This paper portrays advancement and execution of an electronic instrumentation to screen the parameters said above and logging of the information in wanted shape. The framework contains a few savvy sensor hubs. The framework has highlights like online temperature rectification for stickiness, checking and information logging of encompassing RH and temperature at better places of aging room at the same time at a normal rate of 10 information for each moment. The temperature sensor and humidity sensor are connected like a block diagram is bellowed here. 398

Relative moistness will be those proportions from claiming real dampness buzzing around of the most noteworthy measure for dampness that might make held during that air temperature. The hotter the air temperature is, those All the more dampness it cam wood hold. Stickiness sensors use capacitive measurement, which depends for electrical capacitance. Electrical limit is the capacity of two close-by electrical conductors to make a electrical field the middle of them. Those sensors will be made about two metal plates Also holds An non-conductive polymer novel into a film between them. This film collects dampness starting with the air, which reasons the voltage the middle of the two plates on change. These voltage progressions are changed over under advanced readings demonstrating the level about dampness buzzing around. VII.RESULT 400

VIII.CONCLUSION The framework is experiencing test in the manufacturing plant and it is working tastefully. It is watched that temperature and R/H fluctuated every now and then with a most extreme variety of ±2.5 ⁰C for temperature and 8% for R/H. It is discovered that by legitimate control of R/H and temperature the nature of tea can be progressed. The determination of the framework is found as 1% for relative moistness and 1ºC for temperature. The framework is aligned for RH in consistent 250C temperature which gives ± 0.75 % precision on full scale. This framework is helpful for observing the aging procedure parameters which can be utilized for controlling the ideal procedure condition to get wanted tea quality with slight up gradation. There are a few benefits of the created framework over the customary framework as under Minimal effort Online temperature rectification for RH, Simplicity of establishment, little equipment setup, Information logging highlight XI.REFERENCES Journel Papers: [1] S.LSarnot, Need of electronic instrumentation in Tea industries, Technical report.
