Abstract :
An air quality monitoring System (AQMS) for monitoring the concentrations of air pollutant gases has been developed in compliance with IEEE1451.2 standard. The sensor array is implemented using 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 through 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 NCAP. Sensors are recalibrated using the potentiometer adjustment technique of signal conditioning circuits. The AQMS is low cost, energy efficient, and portable.
