Dongyi is an experienced optoelectronic manufacturer, focusing on the production of high-quality infrared receiver heads, infrared receiver tubes and infrared emitting tubes and other products. The infrared receiver is a device used to receive infrared rays, and the LED light-emitting diode is one of the important components. In addition to the infrared receiver, Dongyi has also launched various other models of equipment, such as infrared receiver module, infrared receiver module, remote control receiver and infrared receiver. These devices are not only beautiful in appearance, but also powerful and able to meet the needs of different customers.
Dongyi is a professional optoelectronic manufacturer with rich experience. (Dongyi's IC PD generation process is made of pure gold wire, which has high quality and high reliability.) We have adopted an automatic and machine-oriented production method and applied a paperless management system, which makes the entire factory digital and intelligent. Our overall process includes die bonding, potting testing, and spectroscopic processing) We provide reliable and affordable products to help you meet your factory inspection challenges. In addition, our infrared receivers are available in a variety of shapes and can be individually tailored to your needs. Whether you want a standard nose bridge type or a unique small nose bridge, we have you covered. We also offer a variety of special looks, including slim, mini, straw hat, patch, and corded headers. These appearances can meet the different needs of different customers. If you choose Dongyi, you will not have any regrets. The infrared receiver needs to distinguish its quality, which can first be judged by observing the level of product manufacturing. The product should be very beautifully made, free of flaws and defects, and the quality of the raw materials used is relatively high, presenting a new and shiny surface effect. Secondly, it can be tested by using a multimeter. Connect the receiver to a voltage of 5V, then determine the signal strength of the output by connecting the multimeter and pressing any key on the remote control. Finally, the quality can be judged by checking the pins of the receiver. In general, all three pins of the receiver should be connected to each other in the shielded housing, and at least one of them should be connected to the ground wire to achieve good anti-interference performance.
Regarding the three pins of the receiving head, we take Dongyi's best-selling model 0038 (dot receiving head) as an example, and expand it in detail and present it as follows
The three pins of the IR receiver head 0038 typically include VCC, GND, and OUT. Here's the correct wiring for these three pins: Connect the power supply: Connect the VCC pin to the positive end of the power supply, typically at a voltage of 2.5V to 5V, to provide a stable power supply. Ground: Connect the GND pin to the negative end of the power supply, ensuring a complete current loop is formed. Connect Output: Connect the OUT pin to the input pin of the receiver circuit in order to transmit the received signal to the subsequent processing circuit. Before wiring, it is necessary to determine the positive and negative poles of the power supply to avoid connecting the positive and negative poles of the power supply in the opposite direction, resulting in the burning of the infrared receiver. In addition, the output signal of the OUT pin can be either analog or digital, depending on the size of the IR receiver head. The analog output has a continuous waveform, while the digital output appears as a high or low level change. When connecting, you should make sure that all connections are correct to keep the circuit stable
