Detailed Product Description: | Lancaster Technology Co., Ltd. Shenzhen Rambo was established in 2006, is a collection development, production, sales infrared receiver, infrared emission control, light emitting diodes, monitors dedicated LED array and related electronics components business. Rambo Manchester strength, credit, keep the contract, to ensure product quality, operating characteristics of many varieties and the principle of small profits, win the trust of our customers. Products are widely used: Multimedia, air conditioning, fan, digital photo frame, car audio, remote control toys, satellite receivers, lighting, lights, monitors, night vision products and a variety of electronic products. Infrared receiver infrared receiver circuit is usually composed of red external diode and amplifier circuit, amplifier circuit is usually composed of one manifold and certain components such as resistors and capacitors, and needs to be encapsulated in a metal shield box, so the circuit is more complex, the volume is very small, less than a 7805 large volume! Infrared receiver circuit that infrared receiver and amplifier circuit integrated in one, small size (the size of a medium power transistor fairly) good sealing performance, high sensitivity, it only has three pins are the power positive, negative power and a signal output, its working voltage is about 5V. Just give it connected to the power that is a complete IR receiver amplifier, easy to use. Receiver function principle: amplification, frequency selection, demodulation of several parts, requires the input signal to be modulated signal is already. After it is amplified and demodulated in the receiver output signal directly output the original. Thereby simplifying the circuit to achieve the most! Sensitivity and robustness are very good, it can be said that an ideal device for receiving the infrared signal. The main function of infrared receiver for the IC of a light-receiving element, and its interior is the photodiode (commonly known as the receiver tube) and an integrated infrared receiver IC packaging made common combination, which mainly analog IC design control, generally can receive 850 ~ 1100nm wavelength infrared light, which mainly oriented to receive 940nm. Infrared receiver works as follows: the built-in receiver tube infrared emission emitted light signal is converted to a weak signal, this signal is amplified by the amplifier inside the IC, and then through automatic gain control, band-pass filtering, demodulation, restore the waveform shaping of the original remote control emits a coded signal via the receiver input to the output pin coded identification on the electrical circuit. Receiver generally have three pins: general infrared receiver pin: From left to right: 1.Vout (signal output) 2.GND (negative voltage) 3.Vcc (positive voltage) another from left to right: 1.GND (negative voltage) 2.Vcc (positive voltage) 3.Vout (signal output) there is a pin order, from left to right: 1.Vout (signal output) 2.Vcc (voltage anode) 3.GND (voltage negative) infrared receiver There are several major parameters: 1, the working voltage: receiver on the market now operating voltage IC design are the following: 2.0V ~ 6.5V, (such as low voltage, mainly used battery-powered infrared receiver head) 2.7V ~ 6.5V (IC on the market most of the design, this is mainly used for 3V or 5V supply used electronic products), 4.5V ~ 6.5V (mainly for household appliances products) 2, the center frequency: 32.7KHZ (33KHZ), 36.7KHZ (36KHZ), 37.9KHZ (38KHZ), 40KHZ, 56.7KHZ (56KHZ), the center frequency of the remote receiver to be used with the same frequency, so as to achieve the best reception. 3, the working current: quiescent current 0.1 ~ 0.6mA (for low power products), general product quiescent current at 0.8 ~ 1.5mA 4, receiving distance: This is usually the manufacturer according to their own tests to be identified, without Actual significance, the most important is to see whether the machine platform in their own test results. Advisory QQ: 2355538160 remote parts: the remote part of the working principle is relatively simple, mainly through the transistor to amplify encoding IC modulation, then this signal (pulse wave) via an infrared transmitting tube (940nm wavelength) into optical signals emitted. Now made the circuit of the remote control are: 455K crystal, encoding IC, amplifier transistor, emission control and other major components of several electronic originals, two 3V battery-powered; However, some international companies used the remote control, which encodes the IC has includes a crystal oscillator and amplifier transistor, the circuit design is more convenient, and requires only a battery-driven, more environmentally friendly. |
