描述

該套件由發射器和接收器組成,廣泛用於遙控。

 

基本規格:

  • 頻率:433Mhz。

  • 調製:ASK

  • 接收器數據輸出:高 - 1 / 2Vcc,低 - 0.7v

  • 發射機輸入電壓:3-12V(高電壓=發射功率更大)

  • 發射範圍(5V 工作):室內 40m,露天 100m

用法:

 

流行的鏈接是這樣的:MCU - >編碼器 - >發送器------接收器 - >解碼器 - > MCU,

PT2272(編碼器)和 PT2262(解碼器)是可選的,它們的存在是為了:1)避免在範圍 2)中的多個 RF 鏈路隔離干擾時發生混淆。您可以將編碼和解碼工作集成到 MCU 的兩側。只要周圍沒有 315Mhz 的設備,您可以將其用作直接電纜連接。

 

對於文檔,我們會努力解決這些問題。在此之前,請向我們諮詢任何細節,我們很樂意為您找到答案。我們使用 Sparkfun 的指導來嘗試它們,它是兼容的。唯一的區別在於封裝中一些額外的 GND 引腳。

 

此外,我們將以不同的頻率和容量自行製造更多的射頻模塊。計劃中的下一個基於 cc1100 請向我們介紹您的需求。

Description

The kit is consisted of transmitter and receiver, popular used for remote control.

 

Basic Specification:

  • Frequency: 433Mhz.

  • Modulation: ASK

  • Receiver data output: High - 1/2 Vcc, Low - 0.7v

  • Transmitor input voltage: 3-12V (high voltage = more transmitting power)

  • Transmitting range (work at 5V): 40m indoor, and 100m in open air

Usage:

 

The popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder ->MCU, 

PT2272(Encoder) and PT2262(Decoder) are optional, their existence is to 1)avoid confusing when multiple RF links in range 2) isolate disturbance. You can integrate the encoding and decoding work to the MCUs on both side. Whenever there is no 315Mhz devices around, you may use it as direct cable connection.

 

Excuse for the documentation, we will work on them. Before that, please consult us for any details, we are happy to find the answer for you. We tried them using the guide from Sparkfun, it's compatible. The only difference is in package, of some excess GND pins.

 

Moreover, we will make more RF modules ourselves with different frequency and capacity. The next one in plan is based on cc1100 Please suggest us about your need .
