Optical Sensors are components of an electronic circuit used to detect the presence and/or amount of light present to control various functions. Photo Detectors detect electric signals from light sources, like solar cells or light-emitting diodes (LEDs). Remote Receivers are a type of Photo Detectors that include a photo detector and an amplifier to amplify the signal from the photo detector. A common Photo Detector is the TSOP39133.

TSOP39133 Application Field and Working Principle

The TSOP39133 is a general-purpose infrared receiver for remote control applications used to receive modulated infrared signals from remote control units. This device is based on the advanced techniques of Hamamatsu Corporation’s PIN photodiode and preamplifier. It operates at 3V and 5V supply voltages and is mainly developed for applications such as consumer electronics, remote control units, and communication systems.

The TSOP39133 consists of an infrared photodiode, an amplifier, and a pulse-shaping circuit. The PIN photodiode is made of a semiconductor material optimized to detect infrared (IR) radiation and is usually placed in the center of the receiver device. The amplifier amplifies the small signal current generated by the photodiode. The amplified signal is then sent to a pulse-shaping circuit, which can detect signal pulses from remote control units and convert them into bits for the microprocessor.

The TSOP39133 has a wide operating voltage range (3V-5.5V) which makes it suitable for a variety of applications such as consumer electronics, remote control units, and communication systems. It also has a wide viewing angle of ±45 degrees which makes it suitable for applications that require wide angle operation. It is also capable of receiving data at a rate of up to 500kHz, which makes it ideal for higher data rate applications.

The TSOP39133 is highly sensitive with a wide frequency range allowing for direct frequency input and a wide amplitude range for increased immunity to strong signal interference. It also has an excellent pulse shaping characteristic, an accurate amplitude control, and can work at low thresholds and high frequencies. In addition, it has a low power consumption, making it ideal for low power consumption applications.

Overall, the TSOP39133 is a reliable and cost-effective infrared receiver that is ideal for a myriad of applications, such as remote control units, home appliances, consumer electronics, communication systems, and more. It provides true high-performance with excellent sensitivity, wide frequency range, wide view angle, low power consumption and excellent pulse shape characteristics.
