This module is widely used in sports monitoring, medical devices, and fitness wearables. <\/span><\/li>\n<li><span style=\"font-weight: 400;\">It operates on a low-voltage 1.8V to 3.3V range, ensuring minimal power consumption. For users connecting this to an Arduino Uno, it&#8217;s recommended to handle the I2C pull-up voltage correctly as the onboard resistors are connected to 1.8V. By removing the onboard 4.7k resistors and adding external ones to 3.3V\/5V, you can achieve a stable connection with higher logic microcontrollers. <\/span><\/li>\n<li><span style=\"font-weight: 400;\">Whether you are building a personal health tracker or a biometric project, the MAX30100 offers reliable and fast data acquisition.<\/span><\/li>\n<\/ul>\n<h3><strong>What is the price of MAX30100 Pulse Oximeter and Heart Rate Sensor Module for Arduino &amp; ESP32 in Bangladesh?<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">The latest price of <strong>MAX30100 Pulse Oximeter and Heart Rate Sensor Module<\/strong> in Bangladesh is [product_price id=&#8221;32699&#8243;] taka for 1Pcs of this product.
