Optical sensors enable us to measure the amount of light in a specific area or to detect the presence of light or optical signals. Photo detectors are one of the more common types of optical sensors, consisting of two devices: a photocell and a photodiode. Photocells possess a voltage or a current that varies depending on the amount of light they receive, while photodiodes are used to detect and measure the presence of light.

The TSOP14238 is a type of optical remote receiver that is designed to receive infrared signals that are emitted by a remote control. It has a long range and low-power operation capability, making it a popular choice for many applications. This article will explore the application fields and working principle of the TSOP14238 optical remote receiver.

Application Fields

Due to its long range and low-power operation, the TSOP14238 is a popular choice for remote control applications. It is commonly used by many consumer electronics, such as TVs, audio/video systems, and air conditioners. It is also frequently used in car security systems, in order to control the locking and unlocking of car doors or the triggering of alarms. Additionally, it is also used in robotics systems to control robot motions through the use of a remote control.

Working Principle

The TSOP14238 consists of two main components: a phototransistor and an amplifier. The phototransistor is a light-sensitive device that generates an electrical current when it is exposed to infrared light. When the phototransistor is exposed to infrared light from a remote, it generates a current that is amplified by the amplifier, which then sends a signal to the rest of the circuit. This signal can be used to control various components of the circuit, such as motors, relays, and LEDs.

The TSOP14238 is designed to be very sensitive, and will only be activated when it receives the specific frequencies of infrared light emitted by remote controls. It is designed to ignore all other forms of light, including visible light from lamps and sunlight.

Conclusion

The TSOP14238 is a type of optical remote receiver that is widely used in consumer electronics, car security systems, and robotics systems. It consists of a phototransistor and an amplifier, which amplify a signal which is sent to the rest of the circuit. The TSOP14238 is highly sensitive to only the specific frequencies of infrared light, and is designed to ignore all other forms of light.
