HEART RATE SENSOR

I. Working principle

The heart rate sensor uses a highly integrated process to integrate the force-sensitive element (PVDF piezoelectric film), sensitivity temperature compensation element, temperature sensing element, and signal conditioning circuit into the sensor. The piezoelectric principle collects signals, outputs analog signals, and outputs pulse signals synchronized with the beating of the heart. The heart beats and outputs one positive pulse at a time. A data acquisition system collects the signals and finally displays them on the computer.

II. Specifications

Measuring range:

Pulse range: 0 – 250 bpm (beats per minute); ±2000 mV.

Resolution 1 bpm and 1 mV.

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

This sensor is suitable for biological experiments, such as observing human heart rate in different states.

V.Caution

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

VI.Usage Tips

1. Just press your index finger on the probe when using it.
