Description

The DFRobot Heart Rate Monitor Sensor is designed to measure the electrical activity of the heart, outputting the data as an analog reading. It features an AD8232 chip to generate clear signals from the PR and QT Intervals, enhancing signal clarity in noisy environments. The sensor is compatible with Arduino IDE's "Serial Plotter" feature for visualizing ECG output on a PC. With a Gravity Interface for plug-and-play functionality, it's easy to use with Arduino boards. The sensor operates at 3.3V, making it compatible with various platforms like Raspberry Pi and Intel Edison. However, it's important to note that this product is not a medical device and is not intended for diagnostic or treatment purposes.

  • Heart Rate Monitor Sensor x1
  • Sensor cable - Electrode Pads (3 connector) x1
  • Biomedical Sensor Pad x6
  • PH2.0-3P cable x1

 

Wiring:

NOTE: An ECG signal can be quite noisy due to surrounding muscle activity. The further the sensor pads are from the heart, the more muscle noise you will see. To improve the signal quality, follow these simple tips: Keep sensor pads as close to the heart as you can Make sure the RA and LA sensor pads are on the correct sides of the heart Try not to move too much while taking a measurement Try to use fresh pads for each measurement. The pads lose the ability to pass signals with multiple applications Prepare and clean the area you plan to stick pads. This will help make a good connection (hair is not a good conductor) You may have to adjust sensor placement for different individuals
