Finger Detecting Based on IR Heart Beat Sensor Module

Finger Detecting Based on IR Heart Beat Sensor Module

This unique component is perfect for adding heartbeat sensing to your project. It combines a phototransistor and an infrared LED, providing a varying signal when a finger is placed between them. This simple module is compatible with a wide range of microcontroller-based projects, making it a versatile choice for any project.

The heartbeat detection module works by using a bright infrared LED and a phototransistor to detect the pulse of the finger. With each pulse, a red LED will flash. The pulse monitor operates by turning on the LED on one side of the finger and the phototransistor on the other. As blood flows through the finger, the resistance of the phototransistor will vary slightly, allowing for accurate pulse detection.

It is crucial to keep stray light from entering the phototransistor to ensure accurate readings. This is especially important for home lighting, as most lights operate on 50Hz or 60Hz fluctuations, which can add significant noise to faint heartbeat readings. This product is made in India but originates from China, ensuring high-quality materials and construction.
