Wireless ECG sensor

CMA Wireless ECG sensor measures electrical potentials produced by the heart (electrocardiogram) within a range of 0 to 5 mV. These small voltages are detected through electrodes placed on the skin.
In addition to cardiac activity, the sensor can also measure electrical potentials generated by muscle cells during contraction and relaxation (electromyogram).

The ECG sensor is equipped with an OLED color display which shows sensor information and the measured values. This makes the sensor suitable to use as a standalone measuring instrument.
The sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 lite programs/apps on computers (Windows and Mac), Chromebooks and mobile devices (Android and iOS).

All specifications of the sensor are described it its Product manual.

Suggested biology experiments:

• Monitoring ECG at rest and after mild exercise
• Examining ECG changes in response to mild stimulants
• Analyzing the P, Q, R, S, and T waveforms
• Exploring the effect of different body positions on the ECG
• Recording muscle electrical activity (EMG)
• Investigating the relationship between electrical activity and muscle contraction strength
• Studying the connection between EMG signals and the force exerted by the arm
