Featuring red and infrared LEDs at 660nm and 880nm wavelengths, it uses an I2C interface for easy integration with popular microcontrollers like Arduino and ESP32. Its ultra-low standby current ensures energy efficiency, making it ideal for wearable health devices. This pack includes two modules, perfect for prototyping or backup, empowering makers to build reliable biometric monitoring solutions. ## Description 2Pcs Heart Rate Sensor Module MAX30102 Blood Oxygen Sensor Pulse Detection: desertcart.com: Industrial & Scientific Review: Reliable Pulse and Blood Oxygen Sensors - These MAX30102 modules are excellent for adding biometric sensing to electronics projects. They use the standard I2C interface, which makes them very easy to wire up to an Arduino or ESP32. There are plenty of libraries available, so getting code running to read heart rate and blood oxygen levels is straightforward. I found the readings to be consistent and accurate enough for my wearable prototype. Getting two sensors in the pack is a nice value, allowing for a backup or a second project. A solid choice for health-monitoring DIY builds. Review: Capable heart-rate sensor for skilled tinkerers - This MAX30102 sensor set delivers excellent value, and users with some moderate skills with electronics will find it a strong platform for experimentation. It arrives with both straight and right-angle 2.54-pitch header pins, and the board exposes eight total pins—though only four are required for typical use (VCC at 3.3V, GND, SDA, and SCL). The other four remain available for advanced functions I didn’t need for my project. Soldering the headers is part of the required setup, and the board’s open design makes that step straightforward for anyone equipped with a basic iron and magnifier. To support a prototype biofeedback device for someone with POTS, I wired the sensor to an Arduino Uno and added two 5 kΩ pullup resistors from 3.3V to SDA and SCL. The MAX30102 will not communicate without external pullup resistors, and once those were in place, communication worked immediately. With a simple sketch (ChatGPT assisted), the sensor produced a steady flow of readings with some occasional spike errors which I filtered out with the sketch. The onboard red LED provides clear confirmation that the module is active, and after a few seconds of finger contact, the sensor settles into consistent output. Occasional spikes are normal for optical sensors at this price point and can be easily filtered in software. At $8.99 for two sensors, this is a strong value and provides a spare for future projects. It’s not a plug-and-play classroom module, but a well-designed component meant for makers, and it performs exactly as expected once set up correctly. I look forward to using these to build a heart-rate alert system that can notify my partner and a Bluetooth receiver when her pulse rises above a threshold. The potential applications are wide-open for anyone comfortable with a bit of hands-on work. ## Features - MAX30102 is an integrated module of heart rate monitor biosensor. It integrates a red LED with an infrared LED, a photoelectric detector, an optical device, and a low noise electronic circuit with ambient light suppression. - LED peak wavelength: 660nm/880nm; LED power supply voltage: 3.3~5V; Detection Signal Type: Optical Reflection Signal (PPG); Output Signal Interface: I2C Interface; Communication Interface Voltage: 1.8 ~3.3V~ 5V. - Application: MAX30102 is used in wearable equipment for heart rate and blood oxygen acquisition and detection. It is worn on fingers, earlobes and wrists.The standard I2C compatible communication interface can transmit the collected data to KL25Z and other microcontrollers for heart rate and blood oxygen calculation. - The chip can also turn off the module by software, and the standby current is close to zero, so that the power supply can always be maintained. - Package included:2x MAX30102 Heart Rate Sensor Module ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B094JC48HQ | | Best Sellers Rank | #151,703 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #36 in Sensor Blocks | | Brand | ATNSINC | | Brand Name | ATNSINC | | Color | Black | | Connector Type | Solder | | Customer Reviews | 3.6 out of 5 stars 6 Reviews | | Manufacturer | Atnsinc | | Material | oxygen | | Material Type | oxygen | | Model | MAX30102 | | Mounting Type | PCB Mount | | Number Of Contacts | 5 | | Number Of Poles | 2 | | Number of Positions | 1 | | Part Number | 19146 | | Specification Met | ATEX, CE, CQC, CSA, CSTB, DNV GL, EAC, Energy Rating, FCC, IEC, IECEE CB, ISO 9000, ISO 9001, KEMA-KEUR, LR, MIL-SPEC, RoHS, SAE, SGS, UL, VDE, cUL | | UPC | 701715460423 | | Voltage | 5 Volts | ## Product Details - **Connector Type:** Solder - **Number Of Contacts:** 5 - **Mounting Type:** PCB Mount - **Material:** oxygen - **Color:** Black - **Brand:** ATNSINC - **Voltage:** 5 Volts - **Number Of Poles:** 2 - **Specification Met:** ATEX, CE, CQC, CSA, CSTB, DNV GL, EAC, Energy Rating, FCC, IEC, IECEE CB, ISO 9000, ISO 9001, KEMA-KEUR, LR, MIL-SPEC, RoHS, SAE, SGS, UL, VDE, cUL - **Manufacturer:** Atnsinc ## Images ![2Pcs Heart Rate Sensor Module MAX30102 Blood Oxygen Sensor Pulse Detection - Image 1](https://m.media-amazon.com/images/I/71b-Gw2hUqS.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable Pulse and Blood Oxygen Sensors *by H***̠ on December 21, 2025* These MAX30102 modules are excellent for adding biometric sensing to electronics projects.
