Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →The MAX30102 Black Heart Rate and Blood Oxygen Sensor Module is a compact optical sensor designed to monitor heart rate and estimate blood oxygen saturation (SpO₂). Featuring a black PCB design, this module is ideal for Arduino, ESP32, Raspberry Pi, wearable devices, and DIY health monitoring projects.
The sensor uses red and infrared LEDs to detect changes in blood flow, allowing microcontrollers to process pulse signals and estimate heart rate and SpO₂ levels.
Key Features
-
Heart Rate Monitoring: Measures pulse signals to estimate heart rate in beats per minute (BPM).
-
Blood Oxygen Sensing: Supports SpO₂ estimation using red and infrared light.
-
Black PCB Design: Compact board suitable for small electronic projects.
-
Low Power Consumption: Ideal for portable and battery-powered devices.
-
I²C Communication: Easy connection with Arduino, ESP32, and other supported controllers.
-
Built-in Optical Sensor: Combines LEDs, a photodetector, and signal processing circuits.
-
High Sensitivity: Detects small changes in reflected light caused by blood flow.
