Good accuracy, small footprint

Great little sensor. It fits perfectly on my custom PCB. The only downside is that it requires careful soldering due to its small size.

Solid performance

Works well in my smart watch prototype. Battery consumption is low, which is crucial for my application. Would buy again.

5 FAQ

Q: Does this module come with a breakout board or just the chip?

A: This listing is for the raw TDFN-8 chip component. Breakout boards are sold separately in our store.

Q: What is the sampling rate of this sensor?

A: The conversion time is typically 140ms, allowing for a sampling rate of approximately 7Hz depending on your configuration.

Q: Do you provide sample code for Raspberry Pi?

A: Yes, we have Python examples available in the product documentation section under the 'Downloads' tab.

Q: Can this be used for measuring ambient room temperature?

A: While it can measure ambient temperature, it is optimized specifically for the human body temperature range (37°C to 39°C) for highest accuracy.

Q: Is this compatible with 5V logic levels?

A: No, the MAX30205 operates between 2.7V and 3.3V. You will need a logic level shifter if connecting to a 5V microcontroller.
