Omron's D6T Series MEMS Thermal Sensors are a super-sensitive infrared temperature sensor that makes full use of Omron's proprietary MEMS sensing technology. Unlike typical pyro-electric human presence sensors that rely on motion detection, the D6T thermal sensor is able to detect the presence of stationary humans by detecting body heat, and can therefore be used to automatically switch off unnecessary lighting, air conditioning, etc. when people are not present. As the D6T sensor is also able to monitor the temperature of a room, it can also be used to continually maintain optimal room temperature levels, instantly sense unusual changes in temperature thereby detecting factory line stoppages, or discover areas of overheating for early prevention of fire outbreaks.

While standard thermal sensors are only able to measure temperature at one certain contact point, the D6T can measure the temperature of an entire area contactlessly. Signals generated by infrared rays are usually extremely weak, and high-sensitivity detection is therefore very difficult to achieve. However, Omron has developed and manufactured in-house every part of the new thermal sensor, from the MEMS sensors to ASICs (application-specific integrated circuits) and other application-specific parts, specifically with the aim of ensuring that the D6T is capable of highly sensitive detection.


  • D6Ts are created entirely from Omron's proprietary MEMS, ASIC, and other application-specific parts to ensure high sensitivity.
  • High signal-to-noise ratio: Noise-Equivalent Temperature Difference = 0.14 degrees Celsius
  • Low visual field crosstalk characteristics enable high-precision area temperature detection.
  • Digital I2C output for superior noise immunity
  • OMRON’s unique MEMS and ASIC technologies achieve a high SNR
