Specification

Description

A 38KHz Infrared Transmit Sensor Module is an electronic component that emits infrared (IR) signals at a specific frequency of 38,000 Hertz (38KHz). These modules are commonly used in applications that require wireless communication, remote control, or IR signal transmission.

Here's how they typically work:

IR Emission: The primary function of a 38KHz Infrared Transmit Sensor Module is to emit IR signals. It contains an IR emitter, often an IR LED (Light Emitting Diode), that emits infrared light pulses at a frequency of 38KHz. This specific frequency is widely used in IR communication and remote control systems.

Modulation: The IR signal is typically modulated to have a carrier frequency of 38KHz. This modulation ensures that the signal can be easily distinguished from ambient IR noise and other sources of IR radiation.

Data Encoding: The module can be controlled to transmit specific data patterns using the 38KHz carrier frequency. This is how it communicates information or commands to receiving devices, such as IR receivers in TV remote controls.

Common Applications:

Remote Controls: 38KHz IR modules are often used in remote controls for TVs, home entertainment systems, air conditioners, and other appliances. When you press a button on your remote control, the module emits a specific IR signal that corresponds to the button's function (e.g., changing the channel or adjusting the volume).

Infrared Data Transmission: These modules can be used to transmit data wirelessly between electronic devices, such as between a TV and a set-top box, or for other short-range data communication purposes.
