Description

The Omron D6T-44L-06H is a thermal infrared sensor that detects object surface temperature by measuring far-infrared radiation energy using a MEMS thermopile array. Its sensitivity is wavelength-independent, allowing stable detection across near, mid, and far IR bands without requiring active cooling. The sensor outputs a 16-point temperature Matrix via I2C, enabling simple integration for spatial thermal profiling.

Designed for surface-mount assembly, the module operates within a reference temperature range of 5°C to 45°C for accurate ambient compensation. Its non-contact principle ensures no physical interference with the target, making it suitable for applications requiring hygiene or where contact is impractical.

Key Features

  • MEMS Thermopile Array: 16-pixel (4x4) grid provides basic thermal imaging and hotspot detection.
  • Wide Detection Range: Measures object temperatures from 5°C up to 200°C without contact.
  • Digital I2C Interface: Simplifies wiring and data acquisition with standard two-wire communication.
  • Broad Field of View: 44.2° (horizontal) by 45.7° (vertical) viewing angle for wide-area monitoring.
  • No Cooling Required: Passive thermopile operation eliminates the need for Peltier coolers or fans.
  • Compact SMD Package: Ultra-small 14mm x 18mm footprint for space-constrained designs.
  • Ambient Temperature Compensation: Integrated reference sensor ensures stable readings across 5°C to 45°C environments.

Applications

  • Overheating component detection in factory automation equipment
  • Non-contact temperature monitoring in smart home appliances (e.g., cooking surfaces)
  • Human presence and occupancy sensing for building energy management
  • Thermal profiling for preventive maintenance on electronic assemblies
  • Basic thermal imaging for robotics and machine vision systems

Frequently Asked Questions

What is the operating voltage and I2C logic levels for the D6T-44L-06H sensor?

The Omron D6T-44L-06H typically operates at a supply voltage (Vdd) of 3.3V. Its I2C interface logic levels are compatible with 3.3V microcontrollers. For use with 5V systems, ensure proper logic level conversion is implemented to prevent damage to the sensor's communication lines.

How do I interpret the data from the 4x4 sensor array?

The sensor outputs 16 individual temperature values, each corresponding to a pixel in the 4x4 grid. Data is read via I2C registers. Each pixel's reading represents the average surface temperature of objects within its segment of the field of view, allowing for basic thermal mapping and hotspot localization.

What is the difference between the object and reference temperature detection ranges?

The object temperature range (5°C to 200°C) specifies the surface temperatures the sensor can measure on external targets. The reference temperature range (5°C to 45°C) is the ambient operating environment of the sensor itself, used internally for accurate calibration and compensation of the thermopile readings.

Can this sensor detect humans or motion?

Yes, the D6T-44L-06H can detect human presence based on body heat radiation within its field of view. It is effective for stationary occupancy sensing. For motion detection, firmware must analyze changes in the thermal pattern across the 4x4 array over time, as the sensor itself does not output direct motion signals.
