Abstract:The development of a wireless handheld terminal for indoor gas concentration detection is presented in this paper. The major motivation for this work is to develop a distributed wireless measuring system suitable for metal-oxide semiconductor gas sensors, usually with a wide range resistance (e.g. 0-100M   ), for indoor gas concentration detection. The handheld data acquisition terminal is developed by an ARM-based board and gas concentration detection node is based on MSP430. Experimental results show that the developed wireless handheld terminal is proper for most normal metal-oxide semiconductor gas sensors and has high measurement accuracy (error range: 0.5%-1.0%). In addition, the developed wireless handheld terminal has wireless transmission and control modules which make measurement and control operations more convenient and suitable for indoor air quality environmental inspection at home. ?2010 IEEE.
