Abstract: According to one embodiment, a sensor device includes a switch, a control circuit and an A/D converter. The switch is connected to a sensor element configured to store charge and provided to read the charge stored in the sensor element from the sensor element. The control circuit is configured to control the switch so as to partially and sequentially read the charge stored in the sensor element. The A/D converter is connected to the switch, which is configured to output a digital signal obtained by A/D-converting an analog signal according to the charge, for each charge partially read via the switch.
