This is a dissolved oxygen sensor kit, which is compatible with Arduino micro-controllers. 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, etc. You may also check Liquid Sensor Selection Guide to get better familiar with our liquid sensor series.
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.
Due to the International Import and Export Policy, the corrosive solution (acid & alkaline solution) is not allowed to deliver by air transportation. The filling solution is not included in the kit. You have to purchase it from local shop or deploy the solution by yourself, refer to WiKi FAQ-Q4. It can’t work without filling solution! Please be caution with the purchase!
The oxygen permeable membrane in the membrane cap is sensitive and fragile. Be cautious when handling it. Fingernail and other sharp objects should be avoided.
The DO sensor will consume a little oxygen during the measurement. Please gently stir the solution and let the oxygen to be distributed evenly in the water.
