Indoor Environment Monitoring System (IEMS) for monitoring the concentrations of indoor air pollutant gases and environmental parameters. The sensor array is implemented using the electrochemical sensors. Interface is implemented using the PIC18F4550 microcontroller, it has less power consumption. Network Capable Application Processor (NCAP) implemented in labview9.0 is based on the IEEE 1451.1 standard. The level of indoor environment parameters and information can be seen on the Graphical User Interface (GUI) of the NCAP. Sensors are recalibrated using the technique of signal conditioning circuits. IEMS is low cost, energy efficient and portable.
