Design and Implementation of Cloud services for measuring and monitoring the weather
parameters
Abstract:
Measurement and monitoring of weather parameters play an important role in different fields of
Science and Technology. Also, it becomes essential to monitor the real-time weather condition
of one place from another place. We present the design and implementation of cloud services for
measuring and monitoring the weather parameters. Measured parameters are sent to the Cloud
servers of Thing speak cloud technology (HTTPS) using Wi-Fi communication. Pressure,
Humidity and temperature measurements made in real-time are shown graphically. The software
is developed in Energia integrated development environment (IDE).
Introduction:
The Internet of Things (IoT) is a recent communication, in which a network connects all things
to the internet for communicating through the sensing devices with suitable protocols, and
exchange data with each other by using wireless sensor networks. Embedded systems play a vital
role in IoT; these embedded systems use an admixture of digital and analog subsystems in
gathering information from sensors. In such a complex scenario, the application of the IoT
paradigm shift towards measuring and controlling parameters like humidity, temperature,
pressure, and soil properties etc. that are of paramount importance.
Cloud Computing Technology:
Internet of Things and Cloud Computing technology will provide new opportunities in IoTbased applications and services. In IoT applications, the sensor data will be available in a Cloud
environment. The main use of this Cloud technology is an efficient use of resources and reduces
the cost. It has high flexibility, accessibility and device independence. Present communication
technologies are: wired and wireless. These technologies are helpful in developing the IoT. The
wireless networks are WLAN, ZigBee, Bluetooth, GSM, and NFC which are very useful to add
the things to the internet with minimum hardware and software. Using wireless networks the IoT
user can interact the object with other objects while connected to the internet are identified by
their IP (Internet Protocol) address. These IP addresses are either IPv4/IPv6 version.
Motivation:
The main objective of the present work is to measure the weather parameters using CC3200
LaunchPad. The central core of CC3200 is ARM Processor, which is a 32-bit processor. The
measurement of pressure, humidity & temperature is done with the help of suitable Sensors. The
measured values are sent to Cloud technology with (On-Chip Wi-Fi) wireless network. Cloud
technology automatically displays the measured value from minute to minute and those values
can be accessed from any corner of the world.
Working prototype details:
The wireless sensor networks have several sensing units. The sensing unit gathers the
information from the sensor and communicates with each other via a gateway unit and to send
the measured data to a Cloud for further processing. CC3200 LaunchPad has on-chip Wi-Fi and
it will get an IP address from connection to the Wi-Fi router. Today Wi-Fi is available in most
business, industrial and public sites with high-speed internet connection. Wi-Fi provides a
communication range in the order of 20 m-100 m with data transmission rate in the order of 2–
54 Mbps at 2.4 GHz frequency of ISM band. CC3200 LaunchPad has on-chip 802.11 b/g/n WiFi driver. The Wi-Fi security involves WPA2 personal, WPA2 Enterprise and WPS2. Internet
security includes on-chip SSL 3.0, TLS 1.2, and X.509. The developed system contains the
CC3200 LaunchPad and Pressure sensor,Humidity sensor, Anemometer. The firmware for the
hardware is developed using Energia IDE. The block diagram of the project is shown in figure

Results:
The system is developed to monitor and record the weather parameters like humidity,
pressure and temperature. The measured parameters are uploaded to the cloud using Wi-Fi. In
Thing speak webpage, the humidity, pressure and temperature values are shown in the form of
graphs. Figure 2 shows the graphical representation of values on webpage and mobile.

The displayed data is imported in the form of CSV file which is shown in figure 3 as a screen
shot.

Advantages:
The advantage of present developed is:

Monitor the weather parameters in real-time. This will helpful to taking the necessary
actions based on the data.
Conclusion:
Humidity, pressure and temperature are measured using CC3200 LaunchPad. Results are
more fruitful with minimum loss percentage. So the system is reliable for measuring the both the
parameters in the CloudIoT environment.
