AFBR-S6PY1943中文资料Thin film analog pyroelectric dual-channel sensor with a 3.91 µm / 90 nm filter and a 4.30 µm / 110 nm filter for CO2 (narrow) detection数据手册Broadcom规格书

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-S6PY1943 has a reference channel with a 3.91 µm / 90 nm filter and one channel with a 4.30 µm / 110 nm filter. The main use of this device is CO2 (Narrow) 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.

简介

AFBR-S6PY1943属于传感器变送器的运动传感器-光学。由制造生产的AFBR-S6PY1943运动传感器 - 光学光学运动传感器系列产品使用光（通常是红外光）来检测物体的运动。无源红外型可检测落在传感器上的红外光量的变化，例如温暖的身体穿过传感器视场时引起的变化，而区域反射型可发射光，并检测附近物体反射的光量变化。此系列不包括能检测物体存在性而非运动的产品，例如用于机械安全的光幕。
