GY-906 MLX90614 BAA Non-Contact Infrared Temperature Sensor Module – I²C Digital Output
Product Description
The GY-906 MLX90614 BAA Infrared Temperature Sensor Module measures temperature without requiring physical contact with the target. Based on the MLX90614 infrared thermopile sensor, it detects infrared energy emitted by an object and provides digital temperature readings through an I²C-compatible interface.
This module is useful for embedded electronics, temperature monitoring, thermal detection, automation and DIY projects. It can measure the temperature of suitable surfaces from a distance, making it convenient for applications where direct contact is undesirable.
The GY-906 can be interfaced with compatible microcontrollers such as Arduino and ESP32 for real-time temperature monitoring, data logging and temperature-based control systems.

Important Notes
Object temperature versus ambient temperature: The sensor measures the apparent temperature of the target within its field of view, not simply the surrounding air temperature.
Accuracy: The 0.02°C figure refers to nominal resolution, not guaranteed measurement accuracy. Accuracy depends on the exact MLX90614 variant, target temperature, emissivity and operating conditions.
Medical use: This module should not be assumed to be a certified medical thermometer. Verify the manufacturer's specifications and required approvals before using any temperature sensor for medical decisions.
Voltage compatibility: Check the specific breakout board's supply-voltage rating and I²C logic levels before connecting it to an Arduino or ESP32.
Target conditions: Distance, target size, surface emissivity and ambient conditions can affect readings.
The GY-906 MLX90614 BAA is a useful option for developers who need digital, non-contact temperature measurement in robotics, automation and DIY electronics projects.
