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.

該SparkFun OpenScale是測量重量和溫度的簡單,易用,開源解決方案。它具有讀取多種類型的負載細胞的能力,並提供了一個簡單易用的串行菜單配置校準值,採樣率,時間戳和精度單位。

只要附加任何容量的四線,五線式稱重傳感器,請將OpenScale插入USB端口,在9,600bps打開一個終端窗口,你會立即看到質量讀數。在SparkFun OpenScale將使你把一個負載單元或四個載荷傳感器的惠斯通電橋結構進入DIY電子秤為您的應用。

該OpenScale設計項目和應用中,負載是靜態的(如在SparkFun總部前的蜂窩)或其中需要恆定的讀數,而無需用戶干預(例如,傳送帶系統上)。與配備OpenScale的負載傳感器,可以留在原地了好幾個月,而無需用戶交互!

船上的SparkFun OpenScale是ATMEGA328P微控制器,用於解決您的通信需要和您的數據傳輸到串行終端或數據採集器,如OpenLog ,迷你USB的FT231,用於USB轉串口連接;的HX711,一個24位ADC的電子秤;和TMP102,用於記錄系統的環境溫度。的OpenScale在默認的9,600bps 8-N-1中的TTL電平進行通信,並具有一個波特率1,200bps到1,000,000bps配置。
