Detailed Product Description: | 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. Infrared receiver has several key parameters: 1, the working voltage: now on the market receiver operating voltage of the IC design are the following: 2.0V ~ 6.5V, (such as low voltage, mainly used in 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 used electronic products), 4.5V ~ 6.5V (mainly for household 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. |
