The power supply voltage: 3.3V ~ 5 v Package Included:2 x Heart Rate Pulse Sensor Sensor Module For Arduino Raspberry pi Review: Work great as far as I can tell - I haven't compared them to the genuine Pulse Sensor, but I am getting readings from them via Arduino and can see my pulse on the serial plotter output. Very cool. Review: Need to solder! Comes in three pieces - I am so unhappy with this product! The image shows how it’s all connected but I received it with three pieces! Why do I need to solder everything together when the image shows how it is all pieced together?! ## Features - Pulse sensor Arduino is used to test the heart rate sensor, students, artists,athletes, creator, game developer, or mobile terminal can develop interactive work related to heart rate. - Sensors can be put on the finger or earlobe, through interconnected line can be connected to the Arduino.It also has an open source app, can real time your heart rate graph display. - The power supply voltage: 3.3V ~ 5 v - Package Included: 2 x Heart Rate Pulse Sensor Sensor Module For Arduino Raspberry pi - If You Are Not Satisfied with Your Purchase for Any Reason, Please Feel Free To Contact Us at the Buyer Center or Support Email, 24/7 Quick Reply ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07V6VV8CM | | Best Sellers Rank | #1,111 in Single Board Computers (Computers & Accessories) | | Date First Available | July 11, 2019 | | Item Weight | 0.282 ounces | | Item model number | LY354 | | Manufacturer | Comimark 2Pcs Heart Rate Pulse Sensor Sensor Module for Arduino Raspberry pi | | Package Dimensions | 4.65 x 3.11 x 0.39 inches | ## Images ![Comimark 2Pcs Heart Rate Pulse Sensor Sensor Module for Arduino Raspberry pi - Image 1](https://m.media-amazon.com/images/I/512xCP1VgIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Work great as far as I can tell *by A***E on February 27, 2020* I haven't compared them to the genuine Pulse Sensor, but I am getting readings from them via Arduino and can see my pulse on the serial plotter output. Very cool. ### ⭐ Need to solder! Comes in three pieces *by A***O on March 13, 2025* I am so unhappy with this product! The image shows how it’s all connected but I received it with three pieces! Why do I need to solder everything together when the image shows how it is all pieced together?! ### ⭐⭐⭐⭐ You MUST set the baud rate at 9600 for this to work!!! *by K***K on September 30, 2024* Took a little fiddling but ultimately works as described for a cheap heartbeat sensor. If you've wired and connected this product correctly it will light up green. The reason I had trouble setting it up is that to get a proper signal, you need to set both the serial baud rate in your sketch and the baud rate on your serial monitor/plotter to 9600. Most sketches you'll find for this sensor have a baud rate of 115200 or something like that. I just changed the baud rate and it worked fine. Four stars because I thought based on the picture that I would not have to solder anything. You do have to solder the connectors on to the tabs on the board. ## Frequently Bought Together - Comimark 2Pcs Heart Rate Pulse Sensor Sensor Module for Arduino Raspberry pi - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - Arduino Uno REV3 [A000066] --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/167365914-comimark-2pcs-heart-rate-pulse-sensor-sensor-module-for-arduino](https://www.desertcart.co.uk/products/167365914-comimark-2pcs-heart-rate-pulse-sensor-sensor-module-for-arduino) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
