Grove Alcohol Sensor 酒精感測器

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：問

接收器數據輸出：高 – 1/2 Vcc，低 – 0.7v

Transmitor輸入電壓：3-12V（高電壓=更多發射功率）

發射範圍（工作在5V）：室內40米，露天100米

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，它們的存在是為了避免在範圍2）中的多個RF鏈路隔離干擾時混淆。您可以將編碼和解碼工作集成到兩側的MCU中。每當沒有315Mhz設備時，您可以將其用作直接電纜連接。

對於文檔的藉口，我們將繼續努力。在此之前，請諮詢我們的任何細節，我們很高興為您找到答案。我們使用Sparkfun的指南嘗試了它們，它是兼容的。唯一的區別在於封裝，一些多餘的GND引腳。

此外，我們將自己製造更多不同頻率和容量的射頻模塊。計劃中的下一個是基於cc1100請告訴我們您的需求。

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 .
