Infrared Receiver

The infrared receiver TL1838 (or VS1838B) is a small electronic sensor used to receive signals transmitted from remote controls that operate with infrared rays, such as those used in televisions and air conditioners. It is an essential component in building remote control projects using Arduino or any other microcontroller. This receiver filters signals and only receives those at a frequency of 38 kilohertz, which is the most common frequency in remote devices. It contains three pins: VCC (power), GND (ground), and Signal output, making it easy to connect and use. Technical details: Receiver model: TL1838 / VS1838B, Reception frequency: 38 kilohertz, Operating voltage: 2.7 to 5.5 volts, Reception angle: 90 degrees, Reception distance: up to 18 meters.
