描述
Gravity 模擬類比式溶解氧感測儀組 Analog Dissolved Oxygen Sensor DFRobot 原裝進口
Gravity 模擬類比式溶解氧感測儀組 是一款arduino兼容的溶解氧傳感器，用於測量水中的溶解氧含量，反應水質狀況。可應用於水產養殖、環境檢測、自然科學等領域的水質檢測。俗話說，“養魚先養水，好水養好魚。”良好的水質，對水生物非常重要。溶解氧( Dissolved Oxygen)就是反應水質好壞的重要參數之一。水中的溶解氧值一旦過低，會造成水生物呼吸困難，對其生存造成威脅。

別說明：
由於國際進出口政策，腐蝕性溶液（酸性和鹼性溶液）不允許通過航空運輸。試劑盒中不包含填充溶液。您必須從本地商店購買或自行部署解決方案，請參閱WiKi FAQ-Q4。沒有填充解決方案就無法工作！購買時請小心！
注意：
- 填充液為0.5 mol / L NaOH溶液。使用前需要將其倒入膜蓋中。操作時請小心，因為溶液具有腐蝕性。請戴手套！如果溶液意外掉到皮膚上，請立即用大量清水沖洗皮膚。
- 膜帽中的透氧膜是敏感且易碎的。使用它時要小心。應避免使用指甲和其他尖銳物體。
- DO傳感器在測量過程中會消耗少量氧氣。請輕輕攪拌溶液，讓氧氣均勻分佈在水中。

Gravity: Analog Dissolved Oxygen Sensor / Meter Kit For Arduino
This is a dissolved oxygen sensor kit, which is compatible with Arduino microcontrollers. This product is used to measure the dissolved oxygen in water, to reflect the water quality. It is widely applied in many water quality applications, such as aquaculture, environment monitoring, natural science and so on. You may also check Liquid Sensor Selection Guide to get better familar with our liquid sensor series.
There’s an old saying regarding to keeping fish, “Good fish deserves good water”. Good water quality is very important to the aquatic organisms. Dissolved oxygen is one of the important parameters to reflect the water quality. Low dissolved oxygen in water will lead to difficulty in breathing for aquatic organisms, which may threaten their lives.
Dissolved Oxygen Sensor
We launched a new opensource dissolved oxygen sensor kit, which is compatible with Arduino. This product is used to measure the dissolved oxygen in water, to reflect the water quality. This sensor kit helps you quickly to build your own dissolved oxygen detector.
The probe is a galvanic probe, no need of polarization time, and stay available at any time. The filling solution and membrane cap is replaceable, leading to the low maintenance cost. The signal converter board is plug and play, and has the good compatibility. It can be easily integrated to any control or detecting system.
This product is easy to use with high compatibility. With open-source code and detailed tutorial provided, this product is very suitable for your water projects in detecting the dissolved oxygen concentration for the aquatic organisms.
