The invention relates to a circuit assembly for operating a sensor array, in particular, a gas sensor array for detecting gases, which comprises at least one signal line. According to said invention, a signal line is divided into two parallel line branches with a sensor and a diode, preferably a Schottky diode, arranged in each of said two parallel line branches, whereby the two diodes have opposite electrical polarity. The use of different polarity diodes permits actuation of both sensors through only one signal line. It can be determined if the current flows through one or the other of both sensors by merely polarizing the electrical potential applied to the signal line appropriately.
