SPECIAL INSTRUCTION: Due to the International Import and Export Policy, the corrosive solution (acid & alkaline solution) cannot be delivered by air transportation. The filling solution is not included in the kit. You have to purchase it from the local shop or deploy the solution by yourself, refer to WiKi FAQ-Q4. It can’t work without a filling solution! Please be cautious with the purchase!

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.
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.
Central Control Unit: Arduino Uno (DFRobot Bluno in this case) and Expansion Shield (DFRobot Expansion Shield V7.1 in this case)
Water Sensors: pH (pH probe and pH circuit board); EC (EC probe and EC circuit board); ORP (ORP probe and ORP circuit board); Temperature (temperature probe and temperature circuit board); Dissolved Oxygen (DO probe, BNC and circuit board); real time clock circuit board
Data Storage: Micro-SD module, Micro SD card
Fit and fix: mounting plate, water proof box( 200mm_150mm_75mm), water proof joint
Other parts: Cables (Wires), bread board, bolts and nuts, screws, battery, double-sided adhesive, write on tape, small wrench, spiral cable wrap
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.
