Product Overview

MLX90614ESF-BCC-000-TU is a single-zone non-contact infrared thermometer launched by Melexis, featuring an industry-standard TO-39 package, designed for accurate and reliable temperature measurement. Factory-calibrated across a wide temperature range, this product supports 3V low-voltage power supply and integrates unique gradient compensation to eliminate measurement errors caused by thermal gradients. With a 35° Field of View (FOV), it is adaptable to various complex scenarios. Equipped with an SMBus-compatible digital interface and customizable PWM output, MLX90614ESF-BCC-000-TU can be easily integrated into automotive, industrial, and home appliance devices, enabling high-precision monitoring of object temperature (-70℃~+380℃) and ambient temperature (-40℃~+125℃). It is a cost-effective non-contact temperature measurement solution that balances performance and affordability.

Key Features

• Factory Calibration Across Wide Temperature Ranges, Plug-and-Play：Pre-calibrated for dual temperature ranges at the factory—ambient temperature (Ta) from -40℃ to +125℃ and object temperature (To) from -70℃ to +380℃—no secondary calibration is required for immediate use.
• Gradient Compensation Technology for Stable Measurement：Built-in gradient compensation (a key feature of xCx versions) continuously detects and compensates for thermal gradients within the sensor package, avoiding errors caused by surrounding heat sources (e.g., automotive electronics, industrial equipment) and enhancing measurement reliability in complex environments.
• High Accuracy and High Resolution：Achieves ±0.5℃ accuracy for both Ta and To measurements in the 0℃~+50℃ range; with a measurement resolution of up to 0.02℃, it captures tiny temperature changes, meeting precision monitoring requirements.
• Flexible Digital Interfaces for Easy Integration：Supports SMBus-compatible 2-wire protocol and customizable PWM output. The PWM range can be adjusted via EEPROM (default: -20℃~+120℃), compatible with different microcontrollers and simplifying circuit design.
• Low-Power Design for Battery-Powered Devices：Typical operating current is only 1.3mA, and sleep mode current is as low as 2.5μA (typical value), making it suitable for 3V battery-powered portable devices (e.g., handheld thermometers, wireless sensor nodes).

Technical Specifications

Typical Applications

• Automotive Electronics：MLX90614ESF-BCC-000-TU is ideal for automotive windshield defogging systems and blind-spot detection. The 35° FOV precisely covers target areas, while gradient compensation resists temperature interference from the engine compartment and air conditioning vents, ensuring stable temperature measurement within the -40℃~+125℃ range and improving driving safety.
• Industrial Temperature Control：Suitable for non-contact temperature monitoring of moving parts in industrial equipment (e.g., conveyor belts, motor bearings). It measures temperature without contacting rotating or high-temperature components, and the 0.02℃ high resolution provides early warning of equipment overheating. The SMBus interface supports multi-sensor networking (up to 127 sensors) for synchronous multi-zone monitoring.
• Smart Home & Appliances：Integratable into smart air conditioners, electric ovens, microwaves, and other devices as a core temperature control component. The 3V low-power design is compatible with home appliance power systems, and the PWM output directly links to temperature control logic, avoiding aging issues of contact sensors caused by oil and moisture and extending device lifespan.
• Medical & Healthcare Devices：Used in non-invasive body temperature monitoring devices (e.g., forehead thermometers). High accuracy (±0.5℃) and 3V power supply suit portable designs; the built-in filter resists ambient light interference, ensuring measurement accuracy in hospitals and homes. The non-contact method reduces cross-infection risks.
• Livestock Monitoring：Enables non-contact batch temperature monitoring of livestock in breeding scenarios. The 35° FOV is suitable for medium-distance (0.5~1m) measurement, and the wide temperature range adapts to temperature variations in breeding sheds, helping quickly identify sick livestock.

Why Choose MLX90614ESF-BCC-000-TU ?

• Gradient Compensation Solves Industry Pain Points：Compared to ordinary infrared sensors, its built-in gradient compensation reduces thermal gradient errors by over 80% (as noted in the datasheet for xCx versions), maintaining accurate measurements in heat-source-rich environments (e.g., automobiles, industrial equipment).
• Automotive-Grade Reliability for Harsh Environments：Complies with automotive temperature standards (-40℃~+125℃ operating range) and has an ESD sensitivity of 2kV (per AEC Q100 002), resisting vehicle vibration and electromagnetic interference, meeting automotive industry reliability requirements.
• High Cost-Effectiveness Simplifies Development：Factory calibration eliminates secondary calibration costs; the standard TO-39 package is compatible with conventional soldering processes. Only a 0.1μF decoupling capacitor is needed for stable operation, reducing hardware design complexity and shortening product development cycles.
• Flexible Customization for Multi-Scenario Adaptation：Object emissivity (0.1~1.0) can be customized via EEPROM without blackbody calibration; the PWM output range (e.g., -20℃~+120℃ or user-defined) can be modified through 2 EEPROM cells, adapting to different temperature measurement needs.
• Low Power Consumption for Long Battery Life：Sleep mode current is only 2.5μA (typical), 60% lower than similar 5V sensors. Suitable for battery-powered portable devices (e.g., wireless temperature nodes), extending battery life from 1 day to 1 month (for a 2000mAh battery).
