OMRON Releases Non-Contact D6T MEMS Thermal Sensor
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). As the D6T sensor is also able to monitor the temperature of a room, they 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, 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 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.
With the cutting edge Omron MEMS technology that is utilized in the D6T, we are aiming to contribute to the creation of new advanced energy-saving household appliances as well home and building energy management systems plus a wide variety of factory automation applications.
The D6T thermal sensor will be demonstrated at the Micromachine/MEMS ROBOTECH 2012 exhibition at Tokyo Big Sight from July 11 (Wed) to 13 (Fri).
