描述
SparkFun OpenScale 多功能秤重感測器 美國 SparkFun 原裝進口
SparkFun OpenScale是一個簡單易用的開源解決方案，用於測量重量和溫度。它能夠讀取多種類型的秤重傳感器，並提供一個簡單易用的串行菜單來配置校準值，採樣率，時間戳和精度單位。
只需連接任意容量的四線或五線傳感器，將OpenScale插入USB端口，以9600bps打開終端窗口，即可看到質量讀數。SparkFun OpenScale將使您能夠將惠斯通電橋配置中的稱重傳感器或四個負載傳感器變成適用於您的應用的DIY稱重計。
OpenScale是為負載是靜態的項目和應用程序（如SparkFun總部前面的蜂箱）而設計的，或者在沒有用戶干預的情況下（例如，在傳送帶系統上）需要不斷的讀取。帶有配備的OpenScale的稱重傳感器可以保留數月，無需用戶交互！
船上的SparkFun OpenScale是ATMEGA328P微控制器，用於尋址您的通信需求和數據傳送到串行終端或數據記錄器，如 OpenLog，迷你USB的FT231，用於USB到串行連接; HX711是一款用於電子秤的24位ADC; 和TMP102，用於記錄系統的環境溫度。OpenScale默認的TTL級別為9,600bps 8-N-1，波特率可配置為1,200bps至1,000,000bps。

原廠技術文件與範例
SparkFun OpenScale
The SparkFun OpenScale is a simple-to-use, open source solution for measuring weight and temperature. It has the ability to read multiple types of load cells and offers a simple-to-use serial menu to configure calibration value, sample rate, time stamp and units of precision. Simply attach a four-wire or five-wire load cell of any capacity, plug the OpenScale into a USB port, open a terminal window at 9,600bps, and you’ll immediately see mass readings. The SparkFun OpenScale will enable you to turn a load cell or four load sensors in a Wheatstone bridge configuration into the DIY weigh scale for your application. The OpenScale was designed for projects and applications where the load was static (like the beehive in front of SparkFun HQ) or where constant readings are needed without user intervention (for example, on a conveyor belt system). A load cell with an equipped OpenScale can remain in place for months without needing user interaction! On board the SparkFun OpenScale is the ATmega328P microcontroller, for addressing your communications needs and transferring your data to a serial terminal or to a data logger such as the OpenLog, an FT231 with mini USB, for USB to serial connection; the HX711, a 24-bit ADC for weigh scales; and the TMP102, for recording the ambient temperature of your system. The OpenScale communicates at a TTL level of 9,600bps 8-N-1 by default and possesses a baud rate configurable from 1,200bps to 1,000,000bps. Get Started with the OpenScale Guide
