Monitoring of the environmental parameters is commonly the main issue of Scientifics, Researchers, international organizations and countries as results of the changes of climate. Exchange the information about the environments is very important topic to upgrade the awareness of minimizing the uses of environmental contaminated sources. This paper introduces the design of environmental data share center using wireless sensors network based on IoT protocols. The data share center used to monitor and exchange the environment information collected by sensors nodes and gateways. The sensors nodes detect measure and monitor the environment parameters at distributed different area locations. The wireless sensors network designed using temperature and humidity sensors (DH11), gas sensors and air quality sensors connected to open source hardware platforms supported to MQTT publish/subscribe messaging protocol. The nodes publish the results of the measurements and location of the node to the main station. In the main station, the raspberry pi used as a subscriber to receive the data from the transmission nodes through the broker and present these data at a graphical user interface to display the exact data reading of nodes station.
