Optical sensors are receiving devices that detect events by viewing light. Photodetectors refer to solid- state light-sensitive devices that convert incident light signals into low-level electrical signals. Remote receivers, also known as active sensors, use an infrared light beam to receive data from another device.The TSOP31536 is an infrared remote receiver designed for infrared modulated data transmission applications in the frequency range of 30KHz to 56KHz. It is a monolithic complementary bipolar transistor and photo- diode integrated circuit. The device is manufactured using a silicon gate CMOS, providing low power consumption, high output admittance and a wide bandwidth.The TSOP31536 is applicable in infrared remote control systems used in audio/video equipment. When a modulated signal is received by the device, the output goes to a high logic level. This output can be connected directly to a micro-controller for data decoding and processing. The TSOP31536 operates in a wide temperature range from -30°C to +85°C and requires a minimum power supply of 2.0V and 3.3V. It is available in a variety of packages such as the SOP 6-pin, TSSOP 8-pin and TSSOP 16-pin package.The TSOP31536 is designed to work as an active sensing receiver by detecting incoming modulated IR signals from transmitting sources. It includes a photo-diode and an oscillator circuit used for signal conditioning. The photo-diode changes the incoming IR light waves into an electrical current signal which is then filtered and amplified by the oscillator circuit. The filtered signal is then delivered to an output where it can be read by a micro-controller.The TSOP31536 utilizes an integrated circuit composed of two bipolar transistors, an oscillator and a photo-diode. The operating frequency is fixed, which means that the receiving frequency must accurately match the transmission frequency. The transmitted IR light signal is received by the photo-diode and changes its state from dark to light and back. This fluctuations in the dissipation current cause a variation in the OSC frequency. The small differences in the frequency determines the logic level of the output signal.In conclusion, the TSOP31536 is an ideal device for remote control systems that transmit data in the range from 30KHz to 56KHz. By detecting modulated IR signals, it can convert them into electrical signals for data decoding and processing. With low power consumption and a wide temperature range, it is a reliable and versatile remote receiver that offers excellent performance.
