D6T MEMS Thermal Sensors
Example Applications
Comparison with Pyroelectric Sensor
Able to detect human
(object) motion
Unable to detect stationary
human (object) presence
Able to detect human
(object) motion
Able to detect both stationary and motion
state of humans (objects).

Output signal
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).
Converts temperature readings only when detecting “temperature changes
in the radiant energy” in its field of view.
Converts temperature readings by “continuously detecting the temperature
of radiant energy” in its field of view

The sensors can be used in a wide range of applications, depending on the temperature
measurement range.
