Pressure Sensor IC Piezoresistive pressure sensor makes it easy to obtain high accuracy pressure information by performing temperature correction based on proprietary algorithms via an internal IC. Detects differences in altitude through pressure changes in wearable devices, activity monitors, and advanced detection for indoor navigation in mobile devices. (View Datasheet)
Temperature Sensor ICs ROHM temperature sensor ICs integrate a temperature detection on a single chip, reducing costs for customers.	BDJ0 BDE
Amplifier for Human Body Detector ROHM proximity sensors can be used with pyroelectric infrared sensors in human body sensing applications. (View Datasheet)
Capacitive Switch Control ICs ROHM electrostatic sensor control ICs integrate sensor data processing and application functions, reducing host CPU load.
Touch Screen Control ICs The touch screen controller detects the input of the touch sensor arranged on the LCD screen. These touch sensors easily makes a complex input operation intuitive.
MEMS Sensors Accelerometers and Gyroscopes.
Infrared Image Sensor (LAPIS) The ML8540WD is a medium-resolution (approximately 2,000 pixels) infrared image sensor that allows non-contact temperature measurement of an object and easy obtainment of thermal images. The ML8540WD receives infrared rays from an object at 48x47 (2,256) pixel resolutions, converts them into voltage through a thermopile, and selects pixels in accordance with external CPU clocks to output signals. The built-in op-amp circuit amplifies the infinitesimal voltage of the thermopile for conventional output signal level. Furthermore, the temperature sensor circuit is used to output a temperature-compensated signal by measuring the chip temperature.
UV Sensor (LAPIS) LAPIS Semiconductor developed the UV sensor (ML8511) to detect ultra-violet rays with Si (Silicon) device using the original SOI (silicon on insulator) technology. The ML8511 measures the amount of ultra-violet rays contained in sunlight, and it is used for equipment which displays the suntan by ultra-violet rays, guidance for UV skin care, etc. It is ideal for mobile computing devices, such as smart phones, and watches.
Optical Sensors ROHM's optical sensors have high sensitivity, high reliability phototransistors, infrared light emitting diodes, transmission type photointerruptors and reflective type photointerruptors.
