Description :

-This is a dissolved oxygen sensor kit compatible with Arduino microcontrollers
-It is used to measure the dissolved oxygen in water, which reflects the water quality
-It is widely applied in many water quality applications such as aquaculture, environment monitoring, natural science, etc.
-Good water quality is important to aquatic organisms and dissolved oxygen is an important parameter to reflect water quality.
-The probe is galvanic and does not require polarization time, it is always available.
-The filling solution and membrane cap are replaceable for low maintenance cost.
-The signal converter board is plug-and-play and easy to integrate into any control or detection system.
-Open-source code and detailed tutorial are provided for easy use and integration.
