Abstract :
An Indoor Environment Monitoring System (IEMS) for monitoring the concentrations of indoor air pollutant gases and indoor environmental parameters has been developed in compliance with IEEE1451.2 standard. The sensor array is implemented using the electrochemical sensors. The smart transducer interface module (STIM) is implemented using the PIC18F4550 microcontroller. Network Capable Application Processor (NCAP) implemented in LabVIEW 9.0 is based on the IEEE 1451.1 standard. The NCAP is connected to the STIM via a USB 2.0 Transducer Independent Interface. The level of indoor environment parameters and information regarding the STIM can be seen on the graphical user interface (GUI) of the NCAP. Sensors are recalibrated using the potentiometer adjustment technique of signal conditioning circuits. The IEMS is low cost, energy efficient, and portable.
