Product description
The MLX90636 is a far infrared (FIR), non-contact temperature sensor housed in an ultra-compact Surface-Mount Device (SMD) package (1.8 × 1.8 × 0.75 mm3). Delivering medical-grade accuracy of ±0.2 °C across the human body temperature range, it serves as an ideal sensing foundation for smartwatches and continuous health-monitoring wearables.
Designed to maintain stability in dynamic environments, the sensor strongly resists ambient temperature variations and air turbulence.
To streamline system integration and optimize battery life, the device combines out-of-the-box readiness with deep programmability. It arrives factory-calibrated with constants securely stored in its EEPROM. Through its I2C interface, which supports either 1.2 V or 1.8 V bus voltages, developers can adjust the refresh rate from 0.5 Hz to 32 Hz. Accommodating either a 2.8 V or 3.3 V supply, the sensor minimizes power consumption with an ultra-low sleep current of less than 1.5 µA.
