EKG Sensor

Range: ECG curve from 200 to 4000 µV. 

Resolution ±1μV.



I. Working principle

An electrocardiogram, also called an electrocardiogram or EKG/ ECG, is an electrical signal produced by the heart. The EKG sensor is connected to your body to measure the ECG activity, and the software displays the ECG activity graphically.

II. Specifications

Measuring range: 55 -110 dB(A);

Resolution: 0.1 dB(A)

III.Structure and function

  1. Connect to the datalogger through the lightning interface, support front and back blind plugging, have hot-swappable function, and stable connection and transmission;
  2. Use a dataloggerto connect to computers, mobile phones, tablets and other terminals through wired or wireless methods for data collection;
  3. The sensor supports common systems on the market, such as iOS, Android, windows systems, etc.

IV.Typical applications

An EKG sensor measures the heart’s voltage waveform (voltage generated by the heart’s contractions). Applied research: Measure ECG data while sitting, standing, before and after exercise, while laughing, and before and after using coffee drinks like:

  1. Monitor the electrocardiogram of a person at rest
  2. Study the meaning of P, Q, R, S and T waves
  3. Monitor the electrocardiogram after moderate exercise
  4. Study the electrocardiogram after slight stimulation


This product is suitable for educational use only and is not suitable for industrial, medical, research, or commercial applications.

VI.Usage Tips

  1. Wipe clean the corresponding areas of the skin where the ECG electrodes are to be pasted;
  2. Place the ECG electrode on a clean area of the skin (clean with water, soapy water or alcohol swab);
  3. Attach the ECG electrodes to: the black ground wire is attached to the right forearm, the white negative electrode is attached to the right foot, and the red positive electrode is attached to the left forearm;
  4. Metal or magnetic substances on the body will interfere with or distort the ECG signal;
  5. When the ECG leads are connected to the electrodes, the sensor is ready to acquire data. (Note: The baseline of the ECG waveform will change with the movement of large muscle groups as the ECG sensor collects data. For best results, remain still while collecting data.)
