This paper is an IOT based application which makes use of ESP8266 microcontroller to access sensor data. This paper uses a DHT11 temperature and humidity sensor. Using the DHT11 sensor the temperature and humidity of the room can be sensed. This sensor data is then uploaded onto a server with the help of a ESP8266 WIFI module, so that this data can be accessed by the user. The data uploaded from the sensor can be represented graphically. Depending upon the variations in temperature and humidity in the environment graphs are plotted. Keywords: Sensors, Aurdiuno UNO, Temperature, and Humidity 1 Introduction This paper is based on one of the uses of internet of things. The proposed system produces a solution for monitoring environmental conditions at a particular place and the result will be accessible throughout the world as this is an IoT application. The current application monitors weather through some hardware components like sensors. The benefits of this project are that we can have the access of the data regarding the temperature and humidity around us from anywhere in the world without much struggle. Also we can view the data in various other forms such as tables, charts etc. 2 Related Work Earlier a single master-multi slave microcontroller uni-cast communication method has been developed. i.e the master gave orders to one slave address via the masterslave network that has star topology. At that point the slave who has a similar address which is asked for will react or make a move as per the ace summon. In these interchanges there is just a single ace and one or a few slave which shapes a system. Master allows one to one communication at a time. Slave only communicates with Master if received query and else can t communicate with another. ISSN: ASTL Copyright 2017 SERSC

2 3 Proposed Work The proposed work implements an application which is used for monitoring weather conditions like temperature and humidity of a room and also it can generate reports. The proposed architecture includes the functions of each individual modules developed for weather monitoring system. The proposed model consists of 4-stages. In the first stage to be indentify the information regarding the parameters which is to be monitored for temperature and humidity. In the Second stage the DHT11 sensors are used to operate and controlled based on their sensitivity like fixing the threshold value, periodicity of sensing, messages etc. Stage 3 includes the data acquisition from temperature and humidity sensors. Finally, stage 4 produces the output of the application using Arduino software IDE console. It represents, finding the variations from the sensor retrieval data and based on the threshold value to measure the level of temperature and humidity. Fig. 1.

5 The Serial Plotter gives the graphical representation of temperature and humidity values for the duration of 250 seconds. The blue line represents humidity and red line represents temperature. It is shown in the Figure 5. Fig. 5. Serial Plotter of Temperature and Humidity 5 Conclusion and Future Work We developed a weather reporting system, by making use of an ESP8266 wifi module, DHT11 temperature and humidity sensor along with an Arduino Uno R3 micro controller. This paper is utilized for knowing ecological parameters like temperature and mugginess. The sensor devices have been coordinated and figure the level of temperature and stickiness in the climate and spoke to them utilizing Arduino IDE's serial screen and serial plotter. Following are a few enhancements to the current application so that it will be more effective. A further feature can be added to it where we can attach a buzzer/alarm to it in that such a way that it gives away a audio signal so that the people around will know the change in temperature. Also, we can send an or a message as further indication using internet or by using an android application. 384 Copyright 2017 SERSC
