HS6604 is a high-performance chip that integrates charging management and pyroelectric sensing functions of a single lithium ion battery. It is paired with pyroelectric red External sensors and very few external components constitute passive pyroelectric infrared switches, and fewer external components make them portable applications Ideal for USB power supply and adapter power supply. It can automatically and quickly open all kinds of incandescent lamp, fluorescent lamp, buzzer, from Moving door, electric fan, dryer and automatic washbasin and other devices, especially for enterprises, hotels, shopping malls, storerooms and family aisle, walk Automatic lighting, illumination and alarm systems for sensitive areas such as corridors or for safe areas.
