A WSN has important applications such as remote environmental/mine monitoring and target tracking. This has been enabled by the availability, particularly in recent years, of sensors that are smaller, cheaper, and intelligent. These sensors are equipped with wireless interfaces with which they can communicate with one another to form a network. The design of a WSN depends significantly on the application, and it must consider factors such as the environment/mine, the application’s design objectives, hardware cost, and system constraints. The proposed scheme is to develop a WSN based wireless robot to monitor and store the data for analysis purpose using embedded processor and IOT. The system is used to develop highly functionality, reliability, portability, and secure solutions for small to large embedded devices. Reduce costs, improve product quality, and speed time to market with IOT and predict the analysis based on the data storage in the server. In the recent era the IOT is very much used with the electronic based hardware as well as embedded software to enhance the quality of the product.
A wireless sensor network (WSN) wireless sensor and actuator network (WSAN) are spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location.
The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python.
It is based on SOC(System of Chip) with an ARM cortex processor
[~700 MHz], On chip 256 to 512 MB RAM
The boot media is an SD card
26 GPIO pins
HDMI, Stereo Audio, SD Card, Micro USB, Ethernet
INTERNET OF THINGS (IOT):
The term “Internet of Things” is coined by Kevin Ashton 1999. The Internet of Things (IOT) is an environment in which objects, animals or people are provided with unique identifiers and the ability to transfer data over a network with requiring H2H, H2C, M2M and O2O interaction. IOT has evolved from the convergence of wireless technologies, micro-electromechanical systems (MEMS) with remote monitoring the data and accessibility is enhanced with the help of protocol using HTTP.
RESULT AND CONCLUSION:
We successfully demonstrated Wireless Sensor Network (WSN) Based Robot for Monitoring the Parameter of Environmental/Mine with Internet of Things (IOT). For the said work we have used a Broadcom SoC (System of Chip) with an ARM processor [~700 MHz], a GPU and 256 to 512 MB RAM. SD card, Power supply 5 volt micro USB adapter, and TV/Monitor with DVI or HDMI port, Display connector HDMI cable or HDMI to DVI converter cable, Input through USB Mouse and USB Keyboard, Network Ethernet cable, Case online based model. Include hardware.
