This paper describes a wireless sensor network-based indoor air quality monitoring system. The indoor air quality defines the quality of the environment where people live. Here wireless sensor network serves as the tool for estimating the indoor air quality. The WSN comprises sensor nodes and a coordinator node which communicates using the IEEE 802.15.4 wireless standard ZigBee wireless module. The indoor air quality estimation is done by interfacing CO2, temperature and RH (Relative humidity) sensors with the sensor node. The sensor node gathers the sensor data and reports it to the coordinator for real-time monitoring using a GUI (Graphical user interface) developed in Java NetBeans to run on windows PC. The collected data can be used to maintain the environment parameters by interfacing it to a HVAC (Heating, Ventilation and Air Conditioning) system.
