Description
The DFRobot heart rate sensor is a thumb-sized heart rate monitor designed forArduino microcontrollers.
Thisheart rate monitor sensor is a pulse sensor which is developed based on PPGط¢آ techniques. This is a simple and low-cost optical technique that can be used to detect blood volume changing in the microvascular bed of tissues. It is relatively easy to detect the pulsatile component of the cardiac cycle according to this theory.
The sensor has two holes that you can use to attach to your belt. You can wrap on your finger, wrist, earlobe or other areas where it has contact with your skin.

Aط¢آ Gravityط¢آ Interface is adapted to allow plug&play to ease the barrier of usage. ط¢آ Theط¢آ IO sensor shieldط¢آ is the best option to connect this heart rate sensor with yourط¢آ Arduinoط¢آ or other microcontrollers. Besides, this sensor can also be compatible withط¢آ Raspberry Pi,ط¢آ intel edison, joule and curie by means of 3.3V Input Voltage.ط¢آ
IoT Based Heart Rate Monitoring System is a very basic project on sending the pulse rate to Blynk Application and monitoring it from anywhere.
NOTE:
1. This product is NOT a professional medical device and should not be used to diagnose or treat medical conditions.
2. This sensor is designed to work when the user is not moving. If used while moving it will give inaccurate results.
