Unlike typical pyroelectric 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 (regardless of whether they move or not). Beyond simply monitoring room temperature, the D6T sensor can also be used to continually maintain optimal room temperature levels as well as instantly sense unusual changes in temperature thereby detecting factory line stoppages, or discovering areas of overheating for early prevention of fire outbreaks, etc.

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 without contact. Signals generated by infrared rays are usually extremely weak, and high-sensitivity detection is therefore very difficult to achieve. However, Omron has developed the new thermal sensor, utilizing MEMS sensor technologies, 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.

With the cutting edge MEMS technology that is utilized in the D6T, Omron aims to contribute to the creation of new and advanced energy-saving household appliances, home and building energy management systems, and a wide variety of factory automation applications.
