When the infrared connector is in use, its receiving distance directly affects the signal reception, so now we need to find out the factors that affect the distance of the infrared emitting tube. One, related to infrared emission tubeInfrared emission tube chips generally have 10μ, 12μ, 14μ, and the emission angle is 30, 45, 60 degrees. The larger the chip, the greater the emission power, and the smaller the angle, the more concentrated the infrared. So if you want to choose long-distance infr
Infrared emitting tube (IRLED), also known as infrared emitting diode, belongs to the category of diodes. It is a type that can directly transfer electrical energy to convert electrical energy into near-infrared light (invisible light), and can radiate. It is mainly used for various photoelectric switches, touch screens and remote control transmitter circuits. Its structure and principle are similar to general light-emitting diodes, but the semiconductor materials are different. Generally, galli
Photodiode is a kind of detector that can convert light into electricity or signal. It is widely used in all walks of life in the world. However, there are many photodiodes on the market, and the quality of their use is far from reaching the standard that we use. Anyway, the quality problem of photodiodes is more serious. After we buy photodiodes, we can use methods to check them to make sure. Generally speaking, we start to detect the photodiode, usually the resistance file of the multimeter

Difference 1. The package size is different 1, 5050 refers to the LED lamp beads with a length and width of 5.0*5.0mm. 2, 3030 refers to the 3.0*3.0mm LED lamp beads. difference two, different colors 1, 3030 lamp beads are only monochromatic. 2, 5050 lamp beads can be two-color, one lamp and two-color dual-purpose, good color mixing. Difference three, different power 1, 3030 lamp bead power is 0.2-1W. 2, 5050 lamp bead power is conventional and still 0.2W-0.5W. The above is the introd
Infrared light-emitting diode is a kind of diode that can emit infrared rays, usually used in remote control and other occasions. Commonly used infrared light-emitting diodes are similar in appearance to light-emitting diode LEDs and emit infrared light. The tube voltage drop is about 1.4v, and the working current is generally less than 20mA. In order to adapt to different working voltages, a current-limiting resistor is often connected in the loop. Infrared light-emitting diodes are made o
1. Different resistance Different from the photodiode, when the photoresistor is measured, the resistance on both sides is the same. 2. Different photoelectric effects Photoresistors are compared with photodiodes. The photoelectric effect inside the photoresistor has nothing to do with the electrodes. The photodiode can use DC power, and the sensitivity is related to the semiconductor material and the wavelength of the light. 3. The influence of temperature is different The photoresisto
There are two main reasons for this: The price is cheap. From the price point of view of these different launch tubes, 850nm is more expensive, followed by 880nm, and 940nm is cheaper.In terms of transmit power, 850 is the same, followed by 880, and 940 is weak. From the perspective of the transmitting tube, 850nm is better, and the transmitting distance is proportional to the power; in other words, the receiving end is a transparent receiving tube. This design is also correct, but you can take
Photodiode is a kind of detector, which can convert light into electricity or signal. In various regions of the world, the application range of this product is relatively wide. However, there are many photodiodes on the market, the quality of which is far from the qualified diode standards we use. In any case, the quality problems of photodiodes are more serious. After we buy photodiodes, we can check with methods to determine whether there are any problems. Generally speaking, when we detect
The infrared receiving head is an integrated receiving head composed of an infrared receiving tube and an amplifying circuit. The amplifier usually consists of an integrated block and several resistance capacitors and other components, which need to be sealed in a metal shielding box, so the circuit is complicated and the volume is small. Because in the engineering production process, the circuit board is spot welded first, and then the accessories are inserted, so the engineering needs to un
First, pins and packaging Generally, the infrared receiver has three pins: VCC power positive, GND power negative, and OUT output. Packaging usually includes iron shielding and epoxy plastic packaging, but the shapes are different, including chips, plug-ins, nose bridges, straw hats, cylinders, hemispheres, etc. Different manufacturers have different receiving head pin sequence and shell shape. Second, the main parameters of the infrared receiver The main parameters of the infrared receiv
Compared with traditional incandescent lamps, photodiodes have several advantages. First of all, the photodiode has no filament, which eliminates the possibility of burnout, so it has a longer service life. In addition, the small plastic bulb of the photodiode makes the photodiode more durable. Today's electronic circuits are also easier to use. The light-emitting process of conventional incandescent lamps contains a lot of heat, which is a waste of energy. If you don't use the lamp a
