| Description | The Arduino compatible SEN0161 pH Sensor V2.0 is a clever littlemoduledesigned to measure the acidic and alkaline levels of liquids byidentifyingthe pH, or hydrogen ion concentration index, level of the solution.It usesSensors to measure the level of impedance of the solution instead ofrelyingon a human to compare the results with a specific colour-index. Thisresultsin far more accurate readings, as you can discover the exact pH levelsratherthan deciding on whether the solution looks more yellow or orange –which isparticularly tough if the user is colour-blind or the environmentallightingconditions are not optimal. Although this Electronics Module is part of the DFRobot “Gravity” series,itcan be used for both hobbyist and professional applications due to the easeofuse, compatibility with a wide range of modular electronics, as well astheconsistently high levels of accuracy that it offers. It operates onanyvoltage between 3.3V and 5.5V DC, allowing it to be used with manydifferentMicrocontrollers like the Arduino UNO, and requires no solderingorcomplicated setup procedures to get it working optimally. Just be sure to keep this unit clean, and avoid even small bumps orscratchesto the glass probe on the end. With such a high level of accuracy,even asmall scratch or dent that is invisible to the naked eye can easilyaffect theresults that the probe gives. Fortunately though, the probe comeswith aprotective cap to prevent any unexpected damage, allowing you to keep itsafeand extremely accurate for when you need to get scientific and measurethehydrogen ion concentration index of a solution. With a consumer-centric approach, DFRobot have ensures that this littlekitincludes the pH probe with cap, the signal conversion board, ananaloguesensor, some M3 screws and M3 nylon standoff pillars, two waterproofgasketsand two sets of pH 4.0 and pH 7.0 solutions to calibrate the sensor.Thisensures that all you need to get is a microcontroller in order to getstraightinto the action and measuring the pH levels for agriculture,medicine,chemistry, as well as many other professional and hobbyistapplications. **SEN0161 pH Sensor V2.0 - Arduino Compatible – TechnicalSpecifications:** | – 3.3V to 5.5V DC | – 0 to 14 | – ±0.1 @ 25°C - pH Measuring Response Time
