The color-linear CCD sensor is used in a novel portable poison gas measurement system. The electric circuit based on the color-linear-CCD is designed for data acquisition, considering the small size and low power consumption of the portable measurement system. The circuit is used to obtain the color information of the chemical agent filled in the glass tube. Hence, the type and the concentration of the poison gas can be further obtained. Three main functions of the circuit are: driving the CCD sensor, the A/D conversion and storage of the acquired data, as well as power management. The designed electric circuit has the features of high speed and small power consumption. In our experiments it is used to measure an equivalent of the glass tube full of the chemical agent. The results show that the electric circuit based on the color-linear-CCD can be used to obtain the color information efficiently. The consequent resolution is 0.06 mm in length.
