Optical Sensors - Photo Detectors - Remote Receiver

TSOP2137

The TSOP2137 is an infrared Receiver module, which is typically used in both consumer and industrial applications, including computer peripherals, remote controls, security devices, control systems, medical instruments, and automation. The device is designed to allow users to accurately detect and send remote commands through digital signals, with its high sensitivity filtered for low power operation. It has a wide range of capabilities that are attractive to both consumers and professionals. As part of the TSOP2137 series of modules, this device offers a compact size, excellent sensitivity, low power operation, and signal integration.

Application Field

Infrared (IR) communication is used in many industries, from home entertainment systems to automated safety devices. By using remote IR receivers, users can accurately detect and transmit valuable information over a wide range of applications. In general, the TSOP2137 can be notably seen in equipment such as air conditioners, lighting systems, remote controls, security devices, doors, measuring devices, and much more.

Working Principle

The TSOP2137 is designed to detect modulated infrared signals over a distance of up to 8 meters, and its operating frequency is between 44 kHz and 56 kHz, depending on the type of TSOP2137 model. The module comprises of an infrared sensor, which detects and demodulates the infrared signals from the transmitter, an active low amplifier, which amplifies the demodulated signals from the receiver, and an output stage, which provides a logic level output.The internal LED of the TSOP2137 is connected to the Vcc pin of the Receiver. When the infrared signal is detected, the LED begins to conduct in order to demodulate the signal. The demodulated signal is then amplified and converted to a digital output. This digital output is then used to interpret the received signal and trigger an action accordingly.

Conclusion

The TSOP2137 is a versatile device used in many remote control applications. It offers a wide range of capabilities to its users, including a small size, excellent sensitivity, low power operation, and signal integration. With its wide range of uses, the TSOP2137 is a cost-effective solution for many devices.
