DFROBOT GRAVITY: ****OG DISSOLVED OXYGEN SENSOR / METER KIT FOR ARDUINO

Product Details
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.
There’s an old saying regarding to keeping fish, “Good fish deserves good water”. Good water quality is very important to the aquatic organi******issolved 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.
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.
