The difference between the infrared receiving tube PD and PT
The difference between the infrared receiving tube PD and PT

The photodiode is actually a photoresistor that is very sensitive to light changes. The die of the photodiode is a PN junction with photosensitive properties and has unidirectional conductivity, so the intensity of the light can be used to change the current in the circuit. A photodiode is a semiconductor device that converts an optical signal into an electrical signal. Its core part is also a PN junction. The structure is different from that of a normal diode. In order to facilitate the reception of incident light, the PN junction area is as large as possible, the electrode area is as small as possible, and the junction depth of the PN junction is very shallow, generally less than 1 micron. tube

Precautions for using the infrared receiver
Precautions for using the infrared receiver

There are many types of infrared receiving heads, and the pin definitions are different. Typically, there are three pins (power pin, ground and signal output pins). The receiving head of the corresponding mediation frequency should be selected according to the difference of the modulated carrier at the transmitting end. Below, Chengguangxing photoelectric infrared receiver manufacturers to explain the following considerations for using infrared receivers:

What are the precautions for infrared tube?

First, it should be kept clean and in good condition, especially the spherical emitting part of the front end can neither contain dirt and other dirt, nor will it be damaged by friction。 Otherwise, the infrared light emitted from the die will cause reflection and scattering, which will directly affect the transmission of infrared light。

Classification of infrared light-emitting diodes

What are the classifications of infrared light-emitting diodes? Below, Cheng Guangxing infrared emission tube manufacturers to introduce to you: 1. In-line low-power infrared light-emitting diodes, specifications include: straw hat/helmet, round head, concave, ellipse, tombstone type (2*3*4) bullet, flat head, (3/5/flat head/bread type) Piranha and so on. Second, SMD SMD type infrared light-emitting diodes, conventional models are generally divided into: (3020/3528/5050/5630 these are front-illuminated) / 1016/1024, etc. These are side-illuminated light sources.

What are the requirements of the infrared transmitting tube for the line?
What are the requirements of the infrared transmitting tube for the line?

The infrared emission tube is composed of an infrared light emitting diode, and the PN junction is made of a material with high infrared radiation efficiency (usually using gallium arsenide), and a forward bias is injected into the PN junction to inject a current to excite infrared light, and the spectral power distribution is a central wavelength of 830~ 950nm。 The performance of a light emitting diode is a positive temperature coefficient。 The higher the current, the higher the temperature, and the higher the temperature, the higher the current。 The power of an LED infrared diode is related to the magnitude of the current。 However, when the forward current exceeds the maximum value, the infrared diode emission power is lowered。 The infrared emission tube does not directly contact the object to be measured during the measurement process, so there is no friction, and the advantage is high sensitivity and fast response。
