Phototransistor
Infrared tubes also called infrared emission diode, belongs to the diode classes. It can be directly convert energy near infrared (not visible) and can radiate out light-emitting device, mainly applied in all kinds of photoelectric switch and the radio transmission circuit. Infrared ray tube structure, principle and ordinary light emitting diode similar, but use of semiconductor material is different. Infrared red hair diode usually use GaAs (GaAs), arsenic aluminum, gallium (GaAlAs) and other materials, adopt the whole transparent or light blue, black resin encapsulation.
IR Receiver Modules
Infrared receiver head (also called infrared receiver module, IRM) is integrated infrared receiver PD diode, amplification, filter and comparator output of the IC modules.
Infrared receiver head classification can usually divided into 36,37.9, according to the frequency 40,56.7 Khz can choose according to different needs using different frequency.
Infrared sensor, widely used in home of TV, DVD are no longer manufacture receiving amplifier circuit, so that the infrared sensor simplifies the circuit. A common infrared receiving head shape, all have three pins, namely the power supply is VDD, power negative (GND) and data output (Out). Receiving head of pins arrangement for different and different models for receiving head shape, the difference between different and pins.
