All things are connected properly .but still sensor fails to work ### ⭐⭐⭐⭐⭐ Replacement sensor working perfectly. *by M***R on 13 May 2021* The media could not be loaded. First Sensor was defective. It did not work. I scheduled a return. Allianztec sent me another sensor. This sensor module was already soldered. I connected the sensor and worked perfectly. Really appreciate Allianztec for providing a working replacement sensor. One suggestion for Allianztec - It would be great to provide an option for soldered and unsoldered module selection. ### ⭐ There is a problem with hardware *by K***A on 4 September 2021* Dear seller I think you should avoid sellinhlg this item as there is a hardware problem with the sensor (3 pull up resistors are connected to 1.8v instead of 3.3 volt) and because of this hardware problem this sensor is not working with the micro controllers like arduino. I have seen a lot of people complaining about the sensor not working, the problem might be bcz of this.Thanks --- ## 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.dk/products/281740815-allianztec-heart-rate-sensor-module-max30102-pulse-detection-blood-oxygen](https://www.desertcart.dk/products/281740815-allianztec-heart-rate-sensor-module-max30102-pulse-detection-blood-oxygen) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-27*
