Finger Detection Heart beat Measuring Sensor Module

KY 309 FINGER-DETECTING PULSE HEARTBEAT SENSOR MODULE (IR Based)

The KY-039 Finger Detection Heartbeat Measuring Sensor Module is a simple and affordable component commonly used in DIY electronics and Arduino projects to measure heart rate. It works by detecting the blood flow through a finger placed between an infrared LED and a phototransistor.

Features:

• Components: Infrared LED and phototransistor.
• Design: Specifically designed for heartbeat detection.
• Output: Analog signal directly corresponding to the heartbeat.
• Ease of Use: Plug-and-play with straightforward connections for microcontrollers (e.g., Arduino).

LM358 FINGER-DETECTING PULSE HEARTBEAT SENSOR MODULE (IR Based)

The IC LM358 Finger-Detecting Pulse Heartbeat Sensor Module (IR Based) typically consists of an LM358 operational amplifier integrated into a sensor module designed for detecting heartbeats using infrared (IR) light.

Features:

• Components: Infrared LED, phototransistor, and LM358 operational amplifier.
• Design: Uses the LM358 op-amp for signal amplification and conditioning.
• Output: Amplified analog signal suitable for further processing.
• Flexibility: Requires some understanding of electronics for optimal use.
