Optical Sensors are used to measure light and its primary purpose is to detect changes in the strength and quality of signals, and can be used as motion sensors, light sensors, and enabling the detection of objects that can be seen by a camera or microscope. Photo Detectors are devices that detect and measure light in the form of photons, and are commonly used in light-sensitive electronics components, such as sensors, photovoltaics, and positioners.

The TSOP39230 is a type of remote receiver, and is part of a family of photodetectors used for infrared (IR) communication that can be used in a range of application fields. A core component of the TSOP39230 is an integrated circuit (IC) that has been specifically designed to detect IR radiation from common consumer IR remote controls that use a 38kHz carrier frequency. These ICs have been widely used in consumer electronic devices as universal remote receivers for TVs, DVD players, recording devices and remote-controlled devices. The high sensitivity of the TSOP39230 makes it particularly suitable for use in consumer applications, allowing it to be reliably used in a wide range of environments, with good signal-to-noise ratio.

The working principle behind the TSOP39230 is based on the variation in the current that is produced in the detector when it is exposed to IR radiation. It uses a single photodiode in its design, which is also sensitive to visible light, but has a high rejection of other wavelengths. This makes it ideal for detecting IR radiation from various sources. When the IC is exposed to IR radiation of the carrier frequency, the output current of the photodiode will increase, and then decrease when it is no longer exposed to the radiation. This variation in output current is detected by the IC, which will then output a logic-level signal.

The TSOP39230 is ideal for use in consumer remote control IR receivers, providing very good performance in a range of environments, with good signal-to-noise ratio. The high sensitivity of the TSOP39230 makes it ideal for applications where detecting very small variations in IR signals is necessary. It is also capable of distinguishing multiple transmitters, allowing it to be used in applications where multiple remote controls must be identified. The low power consumption of the IC also makes it suitable for use in battery powered systems.
