Arduino Gravity: 溶解氧感測器 V2 溶解氧含量 水電導率感測器 液體檢測 水質監測

溶解氧感測器 V2  專門用於測量水溶液的電導率 。評估水質狀況,常用於水培、水產養殖、環境水檢測等領域。V2電導率儀為V1的升級版,大大提高了用戶體驗和數據精度。它支持3~5v寬電壓輸入,並兼容5V和3.3V主控板; 由硬件濾波的輸出信號具有低抖動; 激勵源採用交流信號,有效降低極化效應,提高精度,延長探頭壽命; 該軟件庫採用兩點校準方法,可以自動識別標準緩衝解決方案,因此簡單方便。

有了這個產品,主控板(如Arduino)和軟件庫,可以快速建立電導率儀,即插即用,無需焊接。DFRobot提供各種水質傳感器產品,尺寸與接口統一,滿足各類水質檢測的需求,也適合搭建多參數水質檢測儀。

電導率是電阻率的倒數,與物質傳送電流能力的大小有關,在液體中常以電阻的倒數電導來衡量其導電能力的大小。水的電導是衡量水質的一個重要指標,它能反映出水中存在的電解質的程度。

Gravity: Analog Electrical Conductivity Sensor /Meter V2 (K=1)

DFRobot Gravity: analog electrical conductivity meter V2 is specially used to measure the electrical conductivity of aqueous solution, and then to evaluate the water quality, which is often used in water culture, aquaculture, environmental water detectionand other fields. You may also check Liquid Sensor Selection Guide to get better familar with our liquid sensor series. 

This product, as an upgraded version of electrical conductivity meter V1, greatly improves the user experience and data precision. It supports 3~5v wide voltage input, and is compatible with 5V and 3.3V main control board; The output signal filtered by hardware has low jitters; The excitation source adopts AC signal, which effectively reduces the polarization effect, improves the precision and prolongs the life of the probe; The software library uses two-point calibration method, and can automatically identify standard buffer solution, so simple and convenient.

With this product, main control board (such as Arduino) and the software library, you can quickly build an electrical conductivity meter, plug and play, no welding. DFRobot provides a variety of water quality sensor products, uniform size and interface, not only meet the needs of various water quality testing, but also suitable for the DIY of multi-parameter water quality tester.

Conductivity is the reciprocal of the resistance, which is related to the ability of the material to carry the current. In the liquid, the reciprocal of the resistance, the conductivity, is the measure of its ability to conduct electricity. Conductivity is an important parameter of water quality. It can reflect the extent of electrolytes present in water.

In order to ensure the measurement accuracy, it is strongly recommended to add a temperature sensor to measure the temperature, and achieve automatic temperature compensation. DS18B20 waterproof temperature sensor can also be used.

Attention:
1.The probe is a laboratory-grade probe. Do not immerse in liquid for a long time. Otherwise this will shorten the life of the probe.
2.Platinum black layer is attached to the surface of the sheet metal in the probe.It should avoid any object touching it. It can only be washed with distilled water, otherwise the platinum black layer will be damaged, resulting in inaccurate measurement.
