Finger Heart Rate Sensor

Finger Heart Rate Monitor

Finger Heart Rate Monitor Sensor is a sensor with which you can measure heart rate using an analog pin. It consists of a led and a photo transistor. Since the photo transistor resistance changes depending on the blood movement, the pulse can be easily measured in this way. In addition, it is very difficult to get 100% real values ​​with this sensor. An approximate heart rate can be measured.

Finger Pulse Meter Sensor Technical Specifications:

• Operating Voltage: 2.7V - 5.5V
• Frequency: 37.9Khz
• Size: 6.4 x 7.4 x 5.1mm
