This is a dissolved oxygen sensor kit. A dissolved oxygen meter 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.
There’s an old saying regarding keeping fish, “Good fish deserves good water”. Good water quality is very important to aquatic organisms. Dissolved oxygen is one of the important parameters to reflect water quality. Low dissolved oxygen in the water will lead to difficulty in breathing for aquatic organisms, which may threaten their lives.

The probe is galvanic, does not need polarization time, and stays available at any time. The filling solution and membrane cap are replaceable, leading to the low maintenance cost. The signal converter board is plug-and-play and works from 3.3V - 5V which makes it compatible with most popular microcontrollers such as ESP32, Raspberry Pi and Arduino.
You may also check Liquid Sensor Selection Guide to get better familiar with our liquid sensor series.
Dissolved Oxygen Probe:
1. Galvanic probe, no need polarization time
2. Filling solution and membrane cap is replaceable, low maintenance cost
Signal Converter Board:
1. 3.3~5.5V wide-range power supply, compatible with most Arduino microcontroller
2. 0~3.0V analog output, compatible with all microcontrollers with ADC function.
3. Gravity interface, plug, and play, easy to use
Project 1. Analog Dissolved Oxygen Sensor Tutorial | DIY Arduino D.O. Meter
Introduction: Since measuring the parameter of water quality is a complex task, so measuring the dissolved oxygen in water is also not an easy task. That is why the Dissolved Oxygen Meter (DO Meter) available in the market is very expensive. That is why it is important to make your own Dissolved Oxygen Meter. So the Gravity Analog Dissolved Oxygen Sensor from DFRobot is one of the most popular and best Dissolved Oxygen Sensors that are available in the market.
This project will interface Gravity Analog Dissolved Oxygen Sensor with Arduino Board and 0.96″ OLED Display. Firstly, preparing the DO Sensor by filling the 0.5N Sodium Hydroxide Solution, then preparing the sensor for testing. Once the sensor is prepared, go through the Arduino Dissolved Oxygen Sensor calibration code & calibrate the sensor. And then finally making your own Dissolved Oxygen Meter & display the dissolved Oxygen value in OLED Display.
Project 2. Build KnowFlow: automatic water monitor
KnowFlow is the name of this water quality monitoring device, based on Arduino Uno. It can automatically monitor 5 parameters of water: pH, Temperature, Dissolved Oxygen, Electronic Conductivity, ORP.
Project 3. Calibrated Dissolved Oxygen Meter
Introduction: Are you working on a aquaponics or hydroponics project? Or you simply have a fish tank and want your fish to be happy? If yes, you'll probably need a way to measure dissolved Oxygen level.
