OPT3004 是一款用于测量可见光密度的传感器。传感器的光谱响应与人眼的视觉响应紧密匹配,并且具有很高的红外线阻隔率(在入射角较大时)。
OPT3004 是一款用于测量人眼可见光强度的单芯片照度计。OPT3004 器件具有精密的光谱响应和较强的红外阻隔功能,因此能够准确测量人眼可见光的强度,且不受光源影响。对于为追求美观效果而需要将传感器安装在深色玻璃下的工业设计而言,较强的红外阻隔功能还有助于保持高精度。OPT3004 专门针对构建基于光线的人眼般体验的系统而设计,是人眼匹配度低且红外阻隔能力差的光电二极管、光敏电阻或其他环境光传感器首选的理想替代产品。
凭借内置的满量程设置功能,无需手动选择满量程范围即可在 0.01lux 至 83,000lux 范围内进行测量。该功能允许在 23 位有效动态范围内进行光测量。

数字操作可灵活用于系统集成。测量既可连续进行也可单次触发。控制和中断系统可自主操作,允许处理器进入休眠状态,同时传感器会搜索适当的唤醒事件并通过中断引脚报告。数字输出通过兼容 I2C 和 SMBus 的双线制串行接口进行报告。
OPT3004 器件具有低功耗和低电源电压性能,可以提高电池供电系统的电池寿命。
