Omron's microelectromechanical system (MEMS) thermal sensor is an infrared temperature sensor that can measure target surface temperature without touching, by receiving radiant heat from the object with thermopile element(s). To support embedded applications, Omron has implemented thermopile element(s) and application-specific integrated circuits into one package of MEMS thermal sensors to realize an ultra-small module.
Digital output of temperature data detected by the MEMS thermal sensor through I2C communications can reduce both processing load of the master-end microcontroller and the development period. With its non-contact measurement of target surface temperature in the -40° C to 80° C range, MEMS thermal sensors can contribute to energy saving, better amenity, productivity improvement by detecting a human or an object or abnormal heat generation of equipment in various places including a home, building and/or factory.

The D6T sensor measures the surface temperature of objects without touching them when the thermopile element absorbs the amount of radiant energy from the object. The devices can detect human presence by sensing changes in human body temperature with respect to the surrounding temperature, providing data that can be used in a variety of applications including energy-efficient home appliances, security systems and building energy management systems.

The D6T series is a module product that allows connection with only one connector, integrating silicon lens, MEMS thermopile sensor, dedicated analog circuit and logic circuit for conversion into digital temperature data on a small circuit board.
A MEMS thermal sensor can detect abnormal heat generation of factory automation equipment and power board. Through constant monitoring and daily checkup, equipment errors can be quickly recognized and resolved, contributing to reduced part replacement costs and minimized impact of failure on production. Attaching a thermometer or thermistor inside the equipment to monitor temperature can also solve the problem that limits the number of simultaneous monitoring points due to wiring and space restrictions.
If the number of elements is 16 or 8, the sensor can detect temperature transition in the field of view and be used as a motion sensor to operate equipment.
