Good value, minor calibration needed

Solid performance overall. I noticed a slight offset compared to my calibrated thermocouple, but once I applied a software correction factor, it was spot on. The 90-degree FOV is wide, so keep that in mind for small targets.

Fast shipping and great quality

Arrived well-packaged. The metal casing feels durable, and the lens is clean. Tested it immediately on various household items, and the readings were consistent. Highly recommend for prototyping.

Excellent for smart home sensors

Integrated this into my ESP32 based smart home system to monitor radiator temperatures. It responds quickly to changes and the non-contact feature is perfect for retrofiting without drilling holes.

Perfect for Arduino Projects

This sensor module works flawlessly with my Arduino Uno. The I2C communication is stable, and the library support makes reading temperatures incredibly easy. Great accuracy for non-contact measurements.

Reliable for industrial prototyping

We used several of these modules for a thermal monitoring prototype. They handled the voltage fluctuations well and provided steady data over long periods. No failures so far after two weeks of continuous testing.

Works but documentation could be better

The hardware itself is fine, but finding clear pinout diagrams specific to this exact variant took some digging. Once connected correctly, it functions as expected. Just wish the included manual was more detailed.

5 FAQ

Q: Is this compatible with 5V Raspberry Pi GPIO?

A: The sensor operates between 3.3V and 5V, but the I2C logic levels are best kept at 3.3V for Raspberry Pi safety. We recommend using a logic level shifter if powering the VCC at 5V.

Q: Can this measure human body temperature accurately?

A: Yes, within its specified accuracy range. However, for medical-grade diagnostics, please ensure you calibrate it according to local health regulations and use it as a screening tool rather than a diagnostic device.

Q: What is the maximum distance for accurate measurement?

A: The distance depends on the target size due to the 90-degree field of view. Generally, the distance-to-spot ratio is roughly 1:1. For a 1cm target, you should be about 1cm away for optimal accuracy.

Q: Does it require an external pull-up resistor for I2C lines?

A: The GY-906 module typically has onboard pull-up resistors. However, if you experience communication errors, adding external 4.7kΩ pull-up resistors to your SDA and SCL lines is recommended.

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

A: This listing is for the GY-906 module, which includes the MLX90614 sensor mounted on a small PCB breakout board with header pins for easy connection to microcontrollers.
