Design and Implementation of Internet of Things Based Multi-sensor Device

As the technology use in the world progresses the multiple devices and things will co-operate with each other to achieve high reliability and accuracy in the information sharing and processing for better future. To achieve this, the integration of various sensors in single device is designed with the help of standard enclosure and wireless communication technology. The device consists of various physical parameter sensors like temperature, humidity, light intensity, proximity are integrated in single enclosure which communicates its parameters over wireless standard 802.11 a/b/g/n. The access to the information and or sensor data is achieved using Secure Message Queuing Telemetry Transport (SMQTT) standard protocol. The Multi-sensor Device have 32-bit controller based chip ESP8266 programmed to establish the communication with other devices using IBMs Node-Red programming tool running on Raspberry Pi. The data is logged locally on the memory of Raspberry pi. The data is accessible from outside network with secured authentication. The display of sensor data is done on the Node Red based user interface for easy access.
