Home / Products / Light Sensors / Light-to-Frequency


Light-to-Frequency (LTF) Sensors convert light intensity to a digital form for direct interface to a microcontroller. The output of the device is square wave or pulse train whose frequency is linearly proportional to the light intensity. LTF converters are designed for applications such as ambient light measurement, light absorption/reflection in products such as white goods, photographic equipment, colorimetry, chemical analyzers and display contrast controls or any system requiring a wide dynamic range, and/or high resolution digital measurement of light intensity.
