Accurate but sensitive
Works well but needs stable ambient temperature to maintain high precision. Make sure to enclosure it properly.

Great for prototyping
Used this for a health kiosk prototype. Readings are consistent and the I2C interface was easy to implement with our microcontroller.

Precise readings
Compared with a clinical thermometer and the variance was minimal within the specified range. Good for integration.

Easy to interface
Connected to ESP32 easily. Libraries are widely available which saved us a lot of development time.
Q: Are Arduino libraries available for this?
A: Yes, there are multiple open-source libraries available for Arduino and other platforms.
Q: Is this module certified for medical diagnosis?
A: This is a sensor component. Final regulatory compliance depends on your specific system integration and certification.
Q: What is the optimal measuring distance?
A: Distance depends on target size due to the 90-degree FOV. Closer is generally better for small targets.
Q: Can I use 5V logic levels directly?
A: Yes, the module supports 3.3V to 5V, but 3.3V is recommended for I2C stability.
Q: Does this come factory calibrated for human temperature?
A: Yes, the BAA variant is factory calibrated for the human body temperature range.
