The Broadcom thin film pyroelectric infrared (IR) sensors for gas detection and other substance concentration measurements, The main use of this high sensitivity device is CO2 detection. It is High-performance current mode sensor that achieves a signal-to-noise of 10,000 and offers 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 10 GΩ feedback resistor outputting a voltage signal centered on half the supply rail. This product is lead-free and compliant with RoHS.
