Dissolved Oxygen Level Sensor for ArduinoDissolved Oxygen Level Sensor for Arduino by Graylogix is widely used for measuring dissolved oxygen in water. Itâs compatible with Arduino, ESP8266, ESP32, STM32 microcontrollers, and Raspberry Pi. Applications include aquaculture, environmental monitoring, and natural science. In a word it serves the purpose of measuring dissolved oxygen in water to reflect water quality.Calculating Dissolved Oxygen Levels:Expressed in milligrams per liter (mg/L) or parts per million (ppm), given that dissolved oxygen concentration levels are interchangeable, with 1 mg/L equaling 1 ppm. The Dissolved Oxygen Level Sensor kit includes a signal converter board with a BNC connector, especially directly connectable to the Galvanic Probe. This signal converter board amplifies the minor voltage difference eventually to a readable signal detectable by Arduino. With plug-and-play functionality, coupled with the signal converter board ensures good compatibility.To protect the sensitive and fragile oxygen-permeable membrane in the membrane cap, for that reason it is crucial to cover the sensor tip. Also Avoid fingernails and other sharp objects to prevent damage. This sensor can seamlessly integrate into any control or likewise detecting system.Note: lastly a video guide is available for detailed instructions on assembling the DO membrane and filling the membrane cap with KCL solution.Preparing the Dissolved Oxygen Level Sensor Probe:For a new dissolved oxygen probe, first thing to remember begin by adding 7.5% KCL solution into the membrane cap as the filling solution. Follow these steps:Firstly remove the membrane crown.Secondly place the DO membrane on the cap and fix the crown to the electrolyte tube, covering one side of the membrane.Also make sure the membrane is free of wrinkles and remains undamaged or puncturedUnscrew the membrane cap from the probe and fill about 2/3 volume of the cap with KCL solution.Keep the probe in a vertical position concerning the horizontal plane.Carefully screw the cap back onto the probe. To ensure the probe is fully filled with KCL solution and eliminate air bubbles, we accept some solution overflowThe 7.5% KCL solution acts as a suitable electrolyte in the DO Probe.The electrode tube should be free of air bubbles to prevent fluctuations in readings.Check out the data sheet for the calibration process and sample code for Arduino.Technical Specifications of Dissolved Oxygen Level Sensor:      Range 0 to 20.0 ppm      Resolution 0.1 ppm      Accuracy +/- 0.2 ppm to +/- 1 count      DO Sensor Amperometric Gold/Silver Membrane type      PCB Analog output      Power 9 Volts battery Standard Accessories:      DO Electrode 1 No      Signal Converter Board 1 No      Instruction Manual 1 No      DO Membranes 1 Set (4 Nos.)      Potassium Chloride Crystals 2 grams
