In this paper, design and construction processes of a detector have been presented. SnO2 semiconductor sensor has been used at this detector. It has been made in laboratory with vacuum equipment by using CVD method and a heater and a stabilizer circuit of temperature have been used for increasing the sensor temperature and making stable at this temperature. An amplifier circuit coupled to the gas sensor. Also a signal processing circuit and an 8051 programmable micro controller has been used for detection.
