Product Specification
The WH4530A is a light to digital converter which combines an advanced ambient light sensor, an advanced proximity sensor and a high efficiency infra LED light.
Ambient light sensor (ALS) built-in an optical filter for IR rejection, and providing a spectrum which is close to the human eye’s response. ALS can work from dark to direct sunlight, the selectable detect range is about 40dB. Dual-channel output (human eye and clear), so ALS has excellent light ratio under different light conditions.
Proximity sensor (PS) built-in an 940nm optical filter for ambient light immunity, so PS can detect reflected IR light with high precision and excellent rejection.
WH4530A has programmable interrupt function for ALS and PS with threshold based hysteresis.
