The wh4530A is a innovative light distance close to the sensor. It is presented in a unique form of a three -in -one design package. The new rangefinder chip integrates advanced environmental light sensors (ALS), advanced sensor (PS PS (PS)) And high -efficiency infrared LED lights, achieve an integrated design.The chip uses a very small packaging, with the I2C interface mode, shows the high sensitivity and accurate rangefront range, which can cover 0 to 100 cm.Compared with the traditional infrared, ultrasonic and radio frequency close to the sensor, the WH4530A integrates many new technologies, successfully resolving problems such as low sensitivity of the traditional sensitivity, slow response speed, insufficient reliability, and high power consumption., High -precision and excellent anti -interference.This chip uses high -quality optical design, which is highly integrated in ultra -small size, making the overall structure more compact and effectively saving space.Its built -in dual -sensitive elements can automatically attenuate close to the infrared rays. At the same time, it provides a function curve that responds to the human eye, and breaks through the limitations of light sensing technology.

The characteristics are as follows:
■ own I2C interface (400kHz/s fast mode).
■ Power supply voltage is in the range of 2.4V to 3.6V.
■ Environmental light sensor:
-Me spectrum response is close to people's eyes.
-Atflink the fluorescent light.
-Elected gain and resolution (up to 16 bits).
-The sensitivity is high and the detection range is wide.
-Hey -level and light accuracy.
■ Close sensor:
-Igly, the operation distance is less than 100 cm.
-Elected gain and resolution (up to 12 bits).
-A programmable PWM and LED current.
-Smark cross talk calibration.
-The speed mode of improving the response time.

Today, the WH4530A is close to the field of consumer products in the field of consumer products, covering many fields such as smart door locks, access control, mobile phone equipment, computing equipment, consumer electronics, smart homes and other fields.
