PT520 Silicon Phototransistor Ambient Light Sensor
The PT520 is a high-sensitivity ambient light sensor in a DIP package, with a photosensitive peak wavelength of 520nm that simulates human eye sensitivity. It serves as an ideal substitute for traditional CDS photosensitive resistors and is specifically designed for infrared monitoring products to control the activation of infrared lights under low illumination conditions.
