TSOP2338 Application Field and Working Principle

TSOP2338 is an integrated infrared receiver component that operates as optical Remote Receiver, which belongs to a type of Photo Detectors that use optical signals for sensing and detecting objects. It is a small infrared receiver, which along with its small size, high sensitivity of optical wave reception and good anti-jamming capability, is widely applied in fields such as consumer electronics and home security systems. Due to its use of optical radiation as an input, it can achieve reliable distance counting in a reliable and reliable manner.

Application Field

TSOP2338 is mainly used in consumer electronics. It is particularly suitable for implementing the controlling of electronic products such as television, VCD or DVD with the help of a remote control. The product is designed to be used in the fields of consumer electronics, home security, and robotics. In addition, its low power consumption and high integration ensure this component can be used in an energy efficient manner. It is also suitable for applications with a limited space for installation.

Working Principle

The TSOP2338 is an integrated receiver that consists of several components, namely, a PIN photodiode, an amplifier, an LED driver circuit, and an infrared filter. In simple terms, when the remote controller sends out infrared radiation, it will be received by the infrared filter and transmitted to the PIN photodiode. The variation of the received infrared radiation will then be converted into electric signals.

The electric signal is then amplified by the amplifier and sent to the LED driver circuit, which is able to modulate the transmitted signal and control the power supply of the output LED. The output LED will then transmit the output signal through a modulated IR signal of 38 kHz. The receiver will decode the modulated signal and send it to the MCU for further processing.

Conclusion

The TSOP2338 is an integrated and small infrared receiver component that is capable of sensing and detecting objects at a reliable distance. It can be used in fields such as consumer electronics, home security and robotics due to its low power consumption and high integration. Furthermore, the component\'s working principle comprise of several components that modulate the signal received from the transmitted infrared radiation from a remote controller and convert the electric signals to turns on and off the output LED, before it is finally sent to the MCU for further processing.
