Pulse Sensor - Heart Rate Detector Module
Description:
Pulse Sensor is a compact and easy-to-use heart rate sensor module designed to monitor real-time heartbeats by detecting pulses in blood flow through a fingertip or earlobe. Widely used in wearable health and fitness applications, this sensor translates the physical heartbeat into a readable analog signal for microcontrollers such as Arduino, ESP32, or Raspberry Pi.Module is perfect for DIY biomedical projects, fitness monitoring, biofeedback applications, and interactive installations involving heart rate data.
Features:
1. Real-Time Heartbeat Detection
2. Analog Signal Output
3. Integrated Amplifier and Filter
4. Wearable and Compact Design
5. Plug-and-Play with Arduino
6. Visual Feedback (Optional LED)
