HEART RATE CLICK MikroElektronika

2. Soldering the headers Before using your click board , make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 Heart rate click 2 3 4. Essential features Heart rate click is suitable for prototyping wearable devices for fitness or medical applications. The MAX30100 is a low powered IC and it also incorporates ambient light cancellation and motion artefact resilence. For best results, the readings should be taken through the tip of ones finger (the red and IR LED combination is optimized for this application). The readings, however, can Turn the board upside down so that Turn the board upward again. Make sure be negatively impacted by excess motion the bottom side is facing you upwards. to align the headers so that they are and temperature variations. Also, too much Place shorter pins of the header into the perpendicular to the board, then solder the pressure can constrict capillary blood flow appropriate soldering pads. pins carefully. and diminish the reliability of the data. 1. Introduction Heart rate click carries a MAX30100 3. Plugging the board in integrated pulse oximetry and heart rate sensor. Its an optical sensor that derives click Once you have soldered the headers your its readings from emitting two wavelengths board is ready to be placed into the desired of light from two LEDs, then measuring BOARDS mikroBUS socket. Make sure to align the cut the absorbance of pulsing blood through www.mikroe.com in the lower-right part of the board with the a photodetector. The signal is processed markings on the silkscreen at the mikroBUS by a low-noise analog signal processing socket. If all the pins are aligned unit and communicated to the target MCU Heart rate click Manual v100 correctly, push the board all the through the mikroBUS I2C interface. A way into the socket. programmable INT pin is also available. 0100000089354 Uses 3.3V power supply.8. Code examples 5. Schematic Once you have done all the necessary preparations, its time to get your click board up and running.
