Optical Sensors – Photo Detectors – Remote Receiver

The TSOP31356 is a remote receiver, which is part of the family of photo detectors. Optical sensors, or photodetectors, are sensors that convert light energy into electrical signals. They have the ability to sense light, color, and intensity, allowing them to detect and interpret various types of optical signals.

The TSOP31356 is an infrared receiver specifically designed for the detection of infrared light pulses emitted from infrared transmitters. It is able to detect pulses of a specific frequency, such as 38KHz, which is the frequency used by many commercial transmitter/receiver devices. The TSOP31356 is small and compact, making it ideal for applications where space is limited.

Application Field

The TSOP31356 is mainly used for infrared remote control applications that require the detection of IR signals from consumer remote controls. It is also used in various home automation systems for controlling lights, fans, motors, and other devices. The TSOP31356 is also used in many other applications such as burglar and security alarms, medical devices, industrial automation systems, and automotive electronics.

Working Principle

The TSOP31356 consists of an infrared detector and a pre-amplifier circuit. It detects an infrared signal of a specific frequency, such as 38KHz, and amplifies the signal. The amplified signal is then output from the TSOP31356′s output pin. The output of the TSOP31356 is a square wave signal; that is, the signal is initially high, then switches to low when the 38KHz pulse is detected. This signal can then be used to control a device.

The TSOP31356 is an effective, economical, and reliable infrared remote control receiver, suited for a variety of applications. Its ability to detect 38KHz pulses, in combination with its small size and low power consumption, make it an ideal component in many consumer electronics, home automation, and industrial automation implementations.
