SparkFun Pyroelectric Dual Channel Sensor - Fat A

Infrared Detectors Fat A (5.73m/80nm) Fat A Ref (5.60m/80nm).

Pyreos Thin Film Pyroelectric Dual Channel Sensors are ideal for gas detection and other substance concentration measurements. The IR sensors feature exceptionally high responsivity, low microphonics, and class-leading thermal and electrical stability. The high-performance current mode sensors feature a signal to noise of ~10,000 and offer a fast, stable response over a wide operating frequency range. The sensor elements are built into a low noise circuit that has an internal CMOS op-amp, with a 10GΩ feedback resistor outputting a voltage signal centered around half the supply rail.
