VS1838B PDF Datasheet – Infrared Receiver Module

This post explains for the Infrared Receiver. An infrared (IR) receiver is an electronic device designed to receive and decode infrared signals sent by an IR transmitter. Infrared communication involves sending data through infrared light waves, which are not visible to the human eye but can be detected by specialized electronic components like IR receivers. IR receivers are commonly used in various applications, including remote controls, data transmission, and proximity sensing.

The Part Number is VS1838B.

The function of this semiconductor is Infrared Receiver Module.
