简介

液化石油气 (LPG) 气罐广泛应用于家庭厨房,一旦发生爆炸,危险性极大。 除了解何时需要重新加注之外,监测气罐泄漏也至关重要。 LPG 是一种比空气重的气体,放置在气罐下面的智能 LPG 支架可以轻松检测到气体泄漏。 此外,重量检测是通过压力传感器单元来完成的,它可以检测气罐重量,指示何时需要下一次加注。 用户甚至可以通过可选配的 Bluetooth® 低能耗 (LE) 功能访问气罐使用数据或启用自动追加订购。

系统优势:

  • 采用 RA2A1 MCU 的低成本系统,包括内置的运算放大器、高分辨率 ADC(16 位)和 SDADC(24 位),用于精确的重量测量。 Arm® Cortex®-M23 核心 MCU,UART 选项可用于传输数据。
  • 低功耗解决方案可与 7.5V 电池/隔离 AC 反激电源配合使用。
  • 蜂鸣器可指示气体泄漏的安全风险。
