ROHM Sensors

Environment sensors

Environment sensors sense physical quantities, such as ambient light and temperature, and convert them into electrical signals. For example, sensors are used to detect ambient conditions both inside and outside of devices in order to optimize operation, contributing to greater comfort, safety, and energy savings.

Color Sensor

カラーセンサ

WSON008X2120

ROHM color sensors utilize proprietary technology and computational methods to achieve industry-leading IR removal characteristics, reducing the effects of IR rays by over 10x compared with conventional products. This makes it possible to accurately detect the brightness and color temperature even with dark optical windows (low transmittance) that cannot be achieved using conventional color sensors due to the effects of IR rays. The capability of detecting not only brightness but color temperature allows for a more natural display output, improving image quality significantly (i.e. when using a digital camera).

Features

  • Not susceptible to infrared rays
  • Wide light detection range:0.005 to 40k lx
  • High accuracy brightness and color temperature detection even with dark optical windows

Applications

  • Smartphones
  • Tablets
  • Notebook PCs
  • LCD TVs
  • Digital Cameras
  • Display-equipped Devices

Pulse Sensor IC

Pulse Sensor IC

WLGA010V28

ROHM's pulse sensor IC integrates an optical filter ideal for pulse detection on the sensor block. This significantly reduces the effects of noise, including red and infrared rays, making it possible to acquire high-quality pulse signals – even outdoors.
ROHM leverages optical sensor technologies cultivated over many years to significantly improve sensor block sensitivity, enabling support for low-brightness, low VF LEDs and eliminating the need for external circuits (i.e. boost). As a result, a low-power pulse sensor system is achieved that maximizes battery life in wearable devices.

Omnipolar Detection Hall Ics

HVSOF5

HVSOF5

Omnipolar detection hall ICs operate by turning the output ON (Active Low) upon detection of a magnetic field, regardless of polarity (S-/N-pole). This eliminates the need for magnet management (i.e. marking), since the magnet used for omnipolar detection is not limited to a specific polarity. In addition, omnipolar detection Hall ICs with polarity discrimination are offered that feature two outputs, one for detecting S-pole and the other for N-pole magnetic field detection, making it possible to distinguish the polarity of a magnetic field.

Features

  • Offered in a range of sensitivity levels
  • Multiple packages types
  • Models with polarity discrimination available

Applications

  • Tablets
  • Smartphones
