AD8232 心律監測感測器模組測量脈搏 ECG Kit 心跳心電感測器 副廠

AD8232是一款用於ECG及其他生物電測量應用的集成信號 調理模組。該器件設計用於在具有運動或遠端電極放置產 生的雜訊的情況下提取、放大及過濾微弱的生物電信號。 該設計使得超低功耗模數轉換器(ADC)或嵌入式微控制器 能夠輕鬆地採集輸出信號。 AD8232採用雙極點高通濾波器來消除運動偽像和電極半電 池電位。該濾波器與儀錶放大器結構緊密耦合,可實現單 級高增益及高通濾波,從而節約了空間和成本。 AD8232採用一個無使用約束運算放大器來創建一個三極點 低通濾波器,消除了額外的雜訊。使用者可以通過選擇所有 濾波器的截止頻率來滿足不同類型應用的需要。

為了提高系統線路頻率和其他不良干擾的共模抑制性能, AD8232內置一個放大器,用於右腿驅動(RLD)等受驅導聯 應用。 AD8232包含一項快速恢復功能,可以減少高通濾波器原本 較長的建立長尾現象。如果放大器軌電壓發生信號突變(如 導聯脫離情況),AD8232將自動調節為更高的濾波器截止 狀態。該功能讓AD8232可以實現快速恢復,因而在導聯連 接至測量物件的電極之後能夠儘快取得有效的測量值。

The AD8232 Single Lead Heart Rate Monitor is a cost-effective board used to measure the electrical activity of the heart. This electrical activity can be charted as an ECG or Electrocardiogram and output as an analog reading. ECGs can be extremely noisy, the AD8232 Single Lead Heart Rate Monitor acts as an op amp to help obtain a clear signal from the PR and QT Intervals easily.

The AD8232 is an integrated signal conditioning block for ECG and other biopotential measurement applications. It is designed to extract, amplify, and filter small biopotential signals in the presence of noisy conditions, such as those created by motion or remote electrode placement.

The AD8232 Heart Rate Monitor breaks out nine connections from the IC that you can solder pins, wires, or other connectors to. SDN, LO+, LO-, OUTPUT, 3.3V, GND provide essential pins for operating this monitor with an Arduino or other development board. Also provided on this board are RA (Right Arm), LA (Left Arm), and RL (Right Leg) pins to attach and use your own custom sensors. Additionally, there is an LED indicator light that will pulsate to the rhythm of a heart beat. Biomedical Sensor Pads and Sensor Cable are required to use the heart monitor and can be found in the Recommended Products section below.
