智能数字温度传感器是一款高精度数字温度传感器。具备温度自动采样和温度最小值与平均值计算的功能,采样时间和窗口灵活。
对水、土壤和空气数据精度要求高时,这款传感器是理想选择。主要特点是具有完全密封的电子元件、坚韧的II类PVC外壳、海洋级不锈钢探头,是恶劣环境下的理想选择。 型号51163体积小,使用标准的2.5cm(1”)导管和20.3cm(8”)弯角,易部署。具有循环孔,可用于加重,或通过管子或其它小区域拉动传感器。
SDI-12输出为通用型,与任何SDI-12的数据采集器和低功耗应用兼容。如需要使用更长电缆或许多传感器运行,可使用RS-485的接口。
eTracker is a cellular modem and "virtual" cloud-based data logger in one (meaning you don't need to install a separate data logger). Simply connect your sensor and a power source to eTracker and you're done. Configure (or reconfigure) anytime from any Internet-connected device, and use Stevens-Connect to retrieve your data, or forward it to your favorite software system.
