    • A system for detecting precipitation is disclosed. In an embodiment, the system includes a capacitive sensor configured to detect a presence of precipitation, a piezo sensor configured to be powered on in response to detection of the presence of the precipitation by the capacitive sensor, and a processor configured to detect a characteristic of the precipitation based at least in part on an output of the piezo sensor. In an embodiment, a method includes receiving a signal from a piezo sensor, sampling the signal at a sampling rate, determining a frequency domain representation of the sampled signal, determining that a magnitude of a resonant frequency associated with the sampled signal meets a threshold, and determining a valid precipitation event based at least in part on the determination that the magnitude of the resonant frequency meets the threshold.
    • 公开了一种用于检测降水的系统。 在一个实施例中,该系统包括被配置为检测降水的存在的电容传感器,配置为响应于通过电容传感器检测到降水的存在而被通电的压电传感器,以及处理器,被配置为检测 降水至少部分基于压电传感器的输出。 在一个实施例中,一种方法包括从压电传感器接收信号,以采样率采样信号,确定采样信号的频域表示,确定与采样信号相关联的谐振频率的幅度满足阈值, 以及至少部分地基于确定谐振频率的量值满足阈值来确定有效的降水事件。
