Eltec 442-3 Pyroelectric Detector

The 442-3 IR-EYE™ Integrated Sensor is a Lithium Tantalate pyroelectric, parallel opposed, dual element, high gain detector with integral analog signal processing. This high gain detector offers great detection capability over a temperature range of -40 to +70 ºC. This detector has short circuit protection but DOES NOT protect against reverse supply polarity.

Eltec 442-3 Near-infrared Pyroelectric detector. Used to sense body heat or flames. Comes with 1-inch diameter Fresnel lens. Analog output pin provides information about direction of motion of heat source.
Extremely simple to use, this sensor requires no external components, only power and ground connections. The output is an analog signal (0-5V) which can be read by any microcontroller with a spare analog input pin.
