Abstract
Provided is a sensor control apparatus including a main board, a first sensor, a second sensor, and a third sensor, which are connected in series to the main board. The first sensor includes a diagnosis unit configured to perform a failure diagnosis of each of an LED, a phototransistor, and an LED controller. In a case where a failure is detected, the diagnosis unit electrically isolates the first sensor from the series connection, and supplies a power supply voltage to the second sensor.
