LP8

适用于电池供电应用领域的微型二氧化碳传感器模块。宽广的供电电压范围支持多种电池选项。

特点

  • 微型尺寸
  • 可调节的ABC自动基线校正周期
  • 低功耗
  • 多种电池选项

Senseair LP8是一款针对电池供电应用领域的微型二氧化碳传感器模块。客户可以完全控制传感器集成到主机系统的过程,灵活地改变二氧化碳测量周期,从而降低功耗。一次测量仅需3.6mC的电荷(或3.3V电池供电时11.9mJ的能量)。测量间隙应关闭传感器,以尽量减少功耗。如传感器由三节碱性1.5V电池供电,则2.9至5.5V的供电电压即可使其长时间工作。简洁型替代方案是通过单个3.6V Li-SOCl2电池向传感器供电。LP8提供了一种通信协议,允许客户动态更改测量周期并控制ABC(自动基线校正)周期。实现了背景校准和零点校准。
