24ビットA/DコンバータHX711を搭載した計量用ロードセルアンプ。計量器用に設計された24ビットA/DコンバータHX711を搭載したM5Stack用の重さユニットです。ロードセルを用いることにより、M5Stackで重さを測定することができます。マルチプレクサで低ノイズプログラマブルゲインアンプ(PGA)へのチャネルAとチャネルBの差動入力を選択します。チャネルAは、5Vがアナログ電源ピンAVDDに接続されている場合、±20mVまたは±40mVのフルスケールに対応する128または64のゲインを設定できます。チャネルBは固定ゲインが32です。

Description<br />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.<br />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.<br />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!<br />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.<br />Get Started with the OpenScale Guide<br />Features<br />Operating Voltage：5V<br />Operating Ampage：80-100mA<br />Power Cycling above 500ms<br />Selectable 10SPS or 80SPS Output Data Rate<br />Local External Temperature Sensors<br />Fixed Adjustable Gain
