Abstract
A sensor device includes a plurality of row lines WL, a plurality of column lines DL, a plurality of reset lines RL, a plurality of pixel circuits that connect to each one of the plurality of row lines, the plurality of column lines and the plurality of reset lines, and an amplifier circuit. The plurality of pixel circuits respectively includes a pyroelectric element, a reset switch that is driven by the plurality of reset lines and discharges an electric charge of the pyroelectric element, and a pixel selection switch that is driven by the plurality of row lines and outputs a signal, which is based on a change of the electric charge of the pyroelectric element by a discharge, to one of the column lines. The signal based on the change of the electric charge of the pyroelectric element by the discharge is amplified in the amplifier circuit.
