Key features
- Integrated pulse-oximeter and heart-rate biosensor: red and IR LEDs, photodetector and low-noise electronics with ambient-light rejection.
- 1.8 V logic supply plus independent 5.0 V LED supply; wears on finger, earlobe or wrist.
- Standard I2C interface sends readings to Arduino, KL25Z and other MCUs; software shutdown cuts standby current to near zero.
- High integration: LEDs, photodiode, ADC, ambient-light rejection and optical housing in one small, low-power, low-interference module.
- Built-in 18-bit ADC and FIFO reduce MCU load and power; adjustable LED current and sampling rate plus on-chip temperature sensor for SpO2 compensation.
- Glass cover excludes stray light versus the discontinued MAX30100 — the same class of sensor used in the Samsung Galaxy S7.
Frequently asked about this product
Is the I2C Heart Rate & SpO2 Sensor (MAX30102) compatible with Arduino, ESP32 and micro:bit?
Yes. The I2C Heart Rate & SpO2 Sensor (MAX30102) talks over a standard I2C/SPI/UART bus at 3.3 V or 5 V logic, so it connects directly to Arduino (UNO/Nano/ Mega), ESP32, ESP8266 and micro:bit boards. Example sketches for Arduino IDE, Mixly and Mind+ are included, and the bus address can be reconfigured when several modules share one bus.
What voltage does the I2C Heart Rate & SpO2 Sensor (MAX30102) run on?
The I2C Heart Rate & SpO2 Sensor (MAX30102) runs from a standard 3.3-5 V DC supply (USB or the controller’s 5 V rail). It draws only a few milliamps in normal operation, so it is safe to power from the controller board itself for classroom builds.
What projects is the I2C Heart Rate & SpO2 Sensor (MAX30102) good for?
The I2C Heart Rate & SpO2 Sensor (MAX30102) is built for STEM and robotics education: classroom demonstrations, science-fair projects, robotics club builds and competition robots. It pairs with the rest of our module range — same connectors, same voltage, same toolchain — so students move from first circuit to competition robot without changing platforms.
What certification do the robotics and electronics products carry?
Controller boards, sensors and modules ship with CE marking and RoHS-compliant components, and the range is designed for classroom use under teacher supervision. Product-specific test reports and declarations of conformity are available for distributors on request.
What is the minimum order quantity, and can I get a sample first?
These are standard catalogue lines with stable production, so minimums are low and lead times are short. Samples ship within about a week and are normally credited against a first order. Mixed-SKU cartons are accepted for evaluation orders.
