摘要
Power consumption, portability, and system cost are important parameters in designing pervasive measurement systems. With these parameters in mind, wireless environment monitoring system with a capability to monitor greenhouse gases, such as CO, CO2, SOx, NOx, O-2 with environmental parameter is developed. In order to achieve the target design goals, the communication module, the wireless smart transducer interface module, and wireless network capable application processor module were developed based on the IEEE 802.15.4, IEEE 1451.2, and IEEE 1451.1 standards, respectively. The low cost and energy efficient gas sensing modules were successfully developed with improved tolerance to EMF/RFI noise. We defined recalibration of the system at time intervals to ensure that the desired accuracy is maintained. This paper presents the undertaken design detailing solutions to issues raised in previous research.
