Heart Rate Sensor Maxim Integrated MAX30102 – RAK12012

The RAK12012, part of the WisBlock Sensor Series, is a versatile module designed for accurate measurement of heart rate and blood oxygen saturation (SpO₂). It integrates the MAX30102 sensor from Maxim Integrated (Analog Devices), which uses an LED reflective solution for reliable readings.

Thanks to its ultra-low power consumption and robust motion artifact resilience, the RAK12012 is well-suited for wearable devices such as smartwatches, fitness trackers, and portable medical equipment. It features a wide operating temperature range from -40 °C to +85 °C, requires only a 3.3 V power supply, and supports fast data output capabilities.

With its compact dimensions of 25 mm x 35 mm, the RAK12012 is an excellent choice for applications that demand precise and efficient health monitoring in small form factors.
