Great accuracy, small footprint
The size is perfect for wearable prototypes. It took a little time to calibrate initially, but once set up, the data is very reliable. Highly recommend for engineering students.

Stable readings
I was worried about noise in the readings, but this module filters data very well. It responds quickly to temperature changes, making it ideal for real-time monitoring applications.

Excellent value for money
Bought five of these for a batch of smart wristbands. All of them worked out of the box. The documentation provided by the seller was helpful for getting started quickly.

Professional grade component
Using this in a prototype for a patient monitoring system. The precision is impressive for the price point. It integrates seamlessly with our existing ESP32 setup.

Good product, fast shipping
The sensor works as described. The only minor issue is that the pins are quite close together, so you need a steady hand for soldering if you aren't using a breakout board.

Perfect for DIY health projects
This sensor module is incredibly accurate and easy to interface with an Arduino. The I2C communication works flawlessly, and the readings are consistent with my medical thermometer.
Q: Does this come with example code?
A: Yes, the package includes a link to a GitHub repository with example libraries for Arduino, ESP8266, and Raspberry Pi to help you get started immediately.
Q: Can this measure ambient room temperature as well?
A: While primarily optimized for body temperature, it can measure ambient temperatures within its operating range. However, accuracy is highest between 32°C and 42.5°C.
Q: What is the maximum distance for the I2C connection?
A: For standard I2C speeds, we recommend keeping the cable length under 30cm without pull-up resistor adjustments. For longer distances, consider using an I2C extender chip.
Q: Is this module compatible with 5V Arduino boards?
A: Yes, but since the sensor operates at 3.3V, you should use a logic level converter or an I2C level shifter to ensure safe communication with 5V microcontrollers.
Q: How do I change the I2C address if I have multiple sensors?
A: The MAX30205 allows address selection via the A0, A1, and A2 pins. You can configure up to 8 unique addresses on the same bus by connecting these pins to VCC or GND.
