Supply voltage 3-5V I2C communication protocol
Size: 14mm *14mm
Description:
Heart Rate click carries Maxim’s MAX30100 integrated pulse oximetry and heart-rate sensor. It’s an optical senso
r that derives its readings
from emitting two wavelengths of light from two LEDs – a red and an infrared one – then measuring the absorb
ance of pulsing blood through aphotodetector. This particular LED color combination is optimized for reading the data through the tip of one’s finger. The signal is
processed by a low-noise analog signal processing unit and communicated to the target MCU through the mikroBUS™ I2C interface. Developers of
end-user applications should note that the readings can be negatively impacted by excess motion and changes in temperature. Also, too much
pressure can constrict capillary blood flow and therefore diminish the reliability of the data. A programmable INT pin is also available. Uses
3.3V power supply.
Key features:
Optical sensor: IR and red LED combined with photodetector
Measures absorbance of pulsing blood
I2C interface plus INT pin
3.3V-5v power supply
Key Benefits:
Motion artefact resillence
Ambient light cancellation
Ready-to-use examples save development time
Supported in all MikroElektronika compilers
Applications
Developing algorithms for pulse oximetry and heart rate readings through the tip of a finger.

The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
