Air pollution is an issue that is being concerned by publicparticularly in campus environment. This has led the stakeholders in campus to take apart in monitoring the environment condition by carrying out a number of researches on green campus by monitoring the environment condition around campus. The advance of science and technology and planted system principally can cope with the issue by making an application system equipped with a wireless Sensor to monitor the level of air quality. This system supports a number of environment monitoring Sensors integrated in a wireless Sensor network. This research aims to design a Sensory system that is able to monitor the environment quality in the wireless Sensor network in the area of UNDIP (Diponegoro University). The built system uses a number of environment monitoring Sensors interconnected in a wireless Sensor network. The technology-based environment monitor can assist the environmentalists to monitor the campus area. The tool of environment monitor can be in the form of the detecting Sensor of the concentration of CO, NO 2 , and density of dust particles, temperature, air humidity, and light intensity to make the Sensor data identifiable by all environmentalists in everywhere. For this, it requires a media that is able to present the real-time Sensor data. The Sensors used to read the parameters of environment include TGS 2600 Sensor to read the concentration of the carbon monoxide (CO), TGS 2201 Sensor for the nitrogen dioxide (NO 2), GP2Y1010AU0F Sensor for the density of dust particles, BH1750 Sensor for the light intensity, and SHT11 Sensor to read the humidity and temperature of the environment. These Sensor systems use the microcontroller ATmega 2560-based Arduino board as the central of system controller. This system is also equipped with RTC as the timer and GPS as the coordinate of the location where the Sensor system in the non-cable Sensor network is located as a node. The result of this research is the design of Sensor system that is able to read a number of parameters as the control of the air quality of environment around the UNDIP campus well.
