  With the development of sensors, wireless mobile communication, embedded
system, the technologies of the Internet of Things have been widely used in
SmartMeter, public security, intelligent building and so on. Because of its
huge market prospects, the Internet of Things has been paid close attention by
several governments all over the world. IoT facilitates the seamless
integration of wireless sensor networks.
  In this paper, we present an IoT prototype that is built on Raspberry Pi and
uses SMTP (simple mail transfer protocol) for communication. Through this
device, we have proposed a communication system that is less complex and more
secure. It integrates with any "thing" and makes it electronically
communicable. We give an implementation of the prototyping system and system
validation.
