Product Description

This product is retired and we won’t sell it anymore. This page is for reference only.


This module is a component that is capable of detecting infrared radiation (Phototransistor). Since the fire radiates a large number of infrared rays, this sensor will detect them, but this is not its only application. Wherever there are infrared waves, the sensor will detect them (including from solar radiation). Using the built-in comparator on its outputs gives either digital (HIGH / LOW) or analog (0V-5V) signals, depending on the intensity of the IR radiation.
