The non-contact temperature sensor measures the surface temperature of an object. By mounting the signal processing circuit closely to the sensor chip, a low noise temperature measurement is realized.
The module can also be used for detecting the presence of human beings. Todos Technologies non-contact temperature sensor can solve the shortcomings of a conventional pyroelectric sensor, which cannot catch the signal of a stationary person because the sensor detects the change of signal [in principle]. Moreover, Omron’s non-contact temperature sensor keeps detecting the far-infrared ray of an object, while the pyroelectric models do not.
