{"product_id":"sparkfun-mikroe-heart-rate-4-click","title":"SparkFun MIKROE Heart Rate 4 Click","description":"\u003cp\u003eHeart Rate 4 Click carries the MAX30101 high-sensitivity pulse oximeter and heart-rate sensor from Analog Devices. The Click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over I2C interface, with additional functionality provided by INT pin on the mikroBUS� line.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eMAX30101 SENSOR FEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe MAX30101 is an integrated pulse oximetry and heart-rate monitor module. It includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection.\u003c\/p\u003e \u003cp\u003eThe MAX30101 integrates red, green, and IR (infrared) LED drivers to modulate LED pulses for SpO2 and HR measurements. The LED current can be programmed from 0 to 50mA with proper supply voltage.\u003c\/p\u003e \u003cp\u003eThe device includes a proximity function to save power and reduce visible light emission when the user�s finger is not on the sensor.\u003c\/p\u003e \u003cp\u003eThe MAX30101 has an on-chip temperature sensor for calibrating the temperature dependence of the SpO2 subsystem. The temperature sensor has an inherent resolution 0.0625°C.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003ePULSE OXIMETRY OR SPO2\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eOxygen-saturated blood absorbs light differently than unsaturated blood. Pulse oximeters measure the oxygen saturation in one�s blood. Or to put it more precisely the percentage of hemoglobin molecules in blood that is saturated with oxygen.\u003c\/p\u003e \u003cp\u003eIn a healthy adult, this readings go from 94% to 100%.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eHOW THE SENSOR WORKS\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eSince oxygen-saturated blood absorbs more infrared light than red light, and unsaturated blood absorbs more red light than infrared light, the SpO2 readings are calculated by the comparison of the amount of these two types of light.\u003c\/p\u003e \u003cp\u003eIt is best to use your finger for measurement.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eMIKROPLOT\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eYou can use the MikroPlot visualization tool (Windows) to generate a graph from the data sent from the MCU.\u003c\/p\u003e \u003cp\u003eA UART-USB connection is required.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eInterface: GPIO, I\u003csup\u003e2\u003c\/sup\u003eC\u003c\/li\u003e \u003cli\u003eCompatibility: mikroBUS�\u003c\/li\u003e \u003cli\u003eDimensions: 42.9 x 25.4mm\u003c\/li\u003e \u003cli\u003eInput Voltage: 3.3V or 5V\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/e\/e\/b\/2\/7\/Schematic-20285-MIKROE_Heart_Rate_4_Click.pdf\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/2\/a\/7\/7\/f\/max30101.pdf\"\u003eMAX30101 Datasheet\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/www.mikroe.com\/blog\/microcontrollers-have-a-heart-too\"\u003eHeart Rate 3 Click Learn Tutorial\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/libstock.mikroe.com\/projects\/view\/1937\/mikroplot-data-visualization-tool\"\u003eMikroPlot Data Visualization Tool\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/www.mikroe.com\/mikrosdk\"\u003emikroSDK\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/github.com\/MikroElektronika\/mikrosdk_click_v2\/tree\/master\/clicks\/heartrate4\"\u003eGitHub\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40531153059925,"sku":"20285:SEN-20285:spark","price":3545.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/20285_-_MIKROE_Heart_Rate_4-_01.jpg?v=1678246499","url":"https:\/\/www.tanotis.com\/products\/sparkfun-mikroe-heart-rate-4-click","provider":"Tanotis","version":"1.0","type":"link"}
