DFRobot Gravity series Analog Dissolved Oxygen Sensor Meter Kit, 3.3~5.5V compatible with Arduino for aquaculture, environment

Introduction:
  • 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 organisms. Dissolved 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.

SPECIAL INSTRUCTION:

  • 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!
  • Q:How to make 0.5 mol/L NaOH solution?
    A: You need to purchase the NaOH solution firstly, and add 1~2 drops glycerinum to the NaOH solution every 100mL. Only by adding this solution into the probe, can it be ready for use

Note:

  • 1.The filling solution is 0.5 mol/L NaOH solution. You need to pour it in the membrane cap before use. Please be caution with the operation because the solution is corrosive. Please wear gloves! If the solution accidentally drops onto the skin, wash your skin with plenty of water immediately.
  • 2.The oxygen permeable membrane in the membrane cap is sensitive and fragile. Be caution when handling with it. Fingernail and other sharp objects should be avoided.
  • 3.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.
Features:
  • Dissolved Oxygen Probe:
    • 1. Galvanic probe, no need polarization time
    • 2. Filling solution and membrane cap is replaceable, low maintenance cos
  • 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
 
Applications:
  • 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.
