Abstract: A sun detection sensor assembly for attachment to a thermal imaging device, comprising an elongated tubular body having two ends and a sensor, characterized as Sun TECT sensor, attached to one end, the Sun TECT sensor having a tubular body, an IR window positioned at one end of the tubular body, and a photo a infrared photo transistor positioned within the tubular body, opposite the IR window, the infrared photo transistor having a photo sensitive surface for detecting the exposure from sun when the sun is within a field of view of the Sun TECT Sensor, and an automatic ON/OFF mechanism which is activated by the infrared photo transistor and protecting the thermal imaging device from undesired and harmful infrared radiation.
