According to foreign media reports, the SFH 5701A01 of Oslon Optoelectronics Semiconductor is a new type of ambient light sensor. It adopts an integrated circuit design and can adapt to the backlight lighting of the on-board display to facilitate users to read the screen in various weather conditions and brightness levels. Information. The SFH 5701A01 does not need to use a separate power pin, and its chip is designed with a double pin. The SFH 5701A01 uses a special filter encapsulation design that facilitates green light passage and effectively filters out infrared wavelengths. Overall, the sensor can detect the visible spectrum of 450-700 nm. In addition, there is an analog component that uses a linear integrated amplifier that provides a common signal of 135 μA at 100 Lux. See the text for details.

According to foreign media reports, the SFH 5701 A01 of Osram Opto Semiconductors is a new type of ambient light sensor that uses an integrated circuit design and can adapt to the backlighting of the on-board display. It is easy for users to read the information on the screen in various weather conditions and brightness levels.

The SFH 5701A01 does not need to use a separate power pin because its active integrated circuit is powered by a signal current detected by an environmental lamp. Therefore, the chip adopts a two-pin design, replacing three-pin or multi-pin, easy to connect and control. The SFH 5701A01 uses a special filter encapsulation design that facilitates green light passage and effectively filters out infrared wavelengths. (infrayed wavelengs).span>

The design ensures that the components mounted on the surface ensure the adaptability of the human eye to spectral sensitivity, making green the most easily perceived chromatogram. Overall, the sensor can detect the visible spectrum of 450-700 nm. In addition, there is an analog component that uses a linear integrated amplifier that provides a common signal of 135 μA at 100 Lux.

At low illumination(0.01 Lux), its dynamic sensitivity range and sensitivity are high. Under various ambient light conditions, its light measurement value is high, although its size is only 1.25 mm x 2.0 mm x 0.8 mm, However, this type of ambient light sensor can achieve high precision measurement under the condition of dark glasses or plastic cover.span>
