HSDL-9001傳感器變送器的光學傳感器-光電二極管規(guī)格書PDF中文資料

Description

The HSDL-9001 is a low cost analog-output ambient light photo diode in lowest cost miniature Quad-Flat-No Lead (QFN) lead-free surface mount package. It consists of a photodiode, which peaks in human luminosity curve at 550 nm. Hence, it provides an excellent responsivity that is close to the response of human eyes, as shown in figure 2. It provides a design-alternative to the HSDL-9000 digital-output ambient light photo sensor with infinite ambient light detection threshold control. Both the HSDL-9000 and HSDL-9001 are ideal for applications in which the measurement of ambient light is used to control display backlighting. Mobile appliances such as the mobile phones and PDAs that draw heavy current from the display backlighting will benefit from incorporating the HSDL-9000 and HSDL-9001 in their designs to reduce the power consumption significantly.
