Optical sensors are devices that are used to detect light and generate electricity based on it. Photo detectors are a specific type of optical sensor used to detect electromagnetic radiation, primarily visible light from the infrared and ultraviolet spectrums. The TSOP75538WTT is a remote receiver, a specific type of photodetector that is used for detection, modulation, and amplification of weak signals over a distance. It is a type of optical receiver designed to detect remote control encrypted signals from infrared remote controllers.

The TSOP75538WTT is a highly versatile optical receiver. It is able to detect different types of infrared signals from devices such as remote controls, including codes from TRV, TV, air conditioner, satellite, VCD/DVD, and other consumer electronics. It is fully compatible with 38KHz remote controller operating frequency, with a wide range of sensitivities, from 0.2mV/m to 5mV/m, allowing it to detect more powerful signals than many other receivers.

The TSOP75538WTT is also designed to minimize power consumption while extending its lifetime. It has a low power consumption of 18mA, far less than the maximum power draw of 25mA for standard receivers. It also has an extremely low standby current consumption of 0.15mA, making it ideal for power saving applications.

The TSOP75538WTT works on the principle of detecting infrared signals with its Phototransistor (PT) sensor. The PT sensor is composed of an active region which is surrounded by an opaque material. When an infrared signal is emitted from remote control, it is detected by the PT sensor and converted into an electrical signal. The converted electrical signal is then amplified and passed through an external filter to produce an output signal.

The external filter is then used to further filter out the interfering noises from the infrared signal. The output signal is then sent to the processor for further processing. This signal can then be used to control the desired action of the device.

The TSOP75538WTT is a highly reliable and efficient optical receiver that is designed to provide superior performance in remote control detection. With its extremely low power consumption and wide range of sensitivities, this device is ideal for applications such as remote control, security, and broadcasting. The PT sensor ensures that the TSOP75538WTT is able to detect the infrared signal with minimal interference from ambient light even in more challenging environments.
