Unverified监测传感器数量与准确度存在权衡：廉价机型仅测土壤湿度，中高端才含光照/温度/EC电导率（肥力）四合一，但EC探针需定期校准否则读数漂移74% similarUnverified接入智能浇水/自动灌溉方案时，应选带电容传感器+数字信号输出（如支持ADC或蓝牙上报）的土壤湿度传感器，指针机械款无法联动65% similarUnverified电容式土壤传感器的输出电压与含水量非线性，多数消费级产品出厂标定基于标准培养土，用于砂质土或高有机质土时需自行修正映射曲线65% similarUnverified土壤养分(NPK)传感器与家用湿度传感器原理不同，家用款测的多为电导率EC值而非真实NPK含量，宣称测NPK的低价家用款准确度存疑65% similarUnverified有内置湿度传感器且支持恒湿模式（如设定55%RH自动启停）的机型才算真智能，仅有定时开关无传感器的属于伪智能，湿度传感器精度±3%RH以内较可靠64% similar
