AFBR-S6PY0234数据手册传感器变送器的运动传感器-光学规格书PDF

描述 Description

Broadcom's thin film pyroelectric infrared (IR) sensors for gas detection and other substance concentration measurements offer exceptionally high responsivity, low microphonics and class-leading thermal and electrical stability.The analog dual detector AFBR-S6PY0234 has a reference channel with a 3.91 µm / 90 nm filter and one channel with a 4.26 µm / 180 nm filter. The main use of this device is CO2 detection.This high-performance current mode sensor 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.
