Hamamatsu Corporation (Bridgewater, NJ) has introduced a chip-on-board-type illuminance sensor called the S10604. The RoHS-compliant sensor is ideal as an energy-saving sensor for large-screen TV brightness control, as a backlight dimmer in liquid-crystal displays on cell phones, and in other applications where the level of the ambient light is measured. The S10604, which has a package size of 2.0mm × 1.25mm × 0.8mm, is the same size as typical chip resistors.
