MEMS Thermal Sensor D6T-44L-06
High Sensitivity Enables Detection
of Stationary Human Presence • OMRON’s unique MEMS and ASIC technology achieve a high
SNR. • Superior noise immunity with a digital output. • High-precision area temperature detection with low cross-talk
field of view characteristics.
High Accuracy, Smaller Footprint, East to Work WithOMRON's unique MEMS technology allows combining thermopile elements and ASICs into one package resulting to ultra-compact footprint.- *1. IR: Infrared Ray
- *2. SNR: Signal-to-Noise Ratio. Compares the level of a signal to the level of background noise
- *3. As of December 2017, according to OMRON research

SensingInstallation conditionRecommended type: D6T-44L-06 (4×4−element / viewing angle: X=44.2 Y=45.7° / Object temperature range: 0 – 50°C) Comparison with Pyroelectric SensorBoth 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). MEMS thermal sensor (thermopile)Converts temperature readings by “continuously detecting the temperature of radiant energy” in its field of view. Able to detect both stationary and motion state of humans (objects). Pyroelectric sensorConverts temperature readings only when detecting “temperature changes in the radiant energy” in its field of view. Unable to detect stationary human (object) presence
