Great for learning embedded systems
Bought this for a university thesis project. Documentation online is plentiful, which helped me get started quickly. Only wish the cable was included, but that's a minor issue.

Good value, minor calibration needed
The module arrived well-packaged. It required a slight offset calibration in the code to match my reference thermometer, but once set up, it has been very stable. Great for monitoring motor temperatures.

Perfect for Arduino projects
This sensor works flawlessly with my Arduino Uno. The library support is excellent, and the readings are surprisingly accurate for the price point. Highly recommended for DIY thermal projects.

Excellent precision
Using this to monitor my 3D printer bed temperature remotely. The non-contact feature is a game changer for safety. Readings are consistent and match the thermistor data closely.

Fast response time
I am using this on a mobile robot to detect heat sources. The response time is incredibly fast, and the 90-degree field of view is exactly what I needed for broad detection.

Reliable and easy to wire
The pinout is clearly labeled, and the voltage regulator on the board makes it safe to use with 5V logic. No issues after two weeks of continuous operation in our lab.
Q: Does this module work with Raspberry Pi?
A: Yes, the GY-906 uses the I2C protocol, which is fully supported by Raspberry Pi. You just need to connect the SDA and SCL pins to the corresponding GPIO pins on your Pi.
Q: Can this measure human body temperature accurately?
A: While it can detect surface temperature, this industrial-grade sensor is optimized for a wider range (-70°C to 380°C). For precise medical body temperature readings, a sensor specifically calibrated for the narrow human range is recommended.
Q: Is there a library available for ESP32?
A: Yes, there are several open-source libraries compatible with the MLX90614 chip for the ESP32 platform. You can find them easily in the Arduino Library Manager or on GitHub.
Q: Does the package include jumper wires?
A: No, the package includes only the GY-906 sensor module itself. Jumper wires and microcontrollers are sold separately.
Q: What is the maximum distance for accurate measurement?
A: The accuracy depends on the target size relative to the distance due to the 90-degree field of view. For best results, ensure the target completely fills the sensor's view; typically, this means staying within 10-20 cm for small objects.
