D6T MEMS Thermal Sensors

Contactless Measurement OMRON MEMS Thermal Sensors are able to detect the slightest temperature changes

MEMS Thermal (IR sensor) measures the surface temperature of objects without touching them when the thermopile element absorbs the amount of radiant energy from the object.

Comparison with Pyroelectric Sensor

Both the pyroelectric sensor and non-contact MEMS thermal sensor can detect even the slightest amount of radiant energy from objects such as infrared radiation and convert them into temperature readings. However, unlike pyroelectric sensor that relies on motion detection, non-contact MEMS thermal sensor is able to detect the presence of stationary humans (or objects).
