It has an LED that works as the Power Indicator, a pH sensor, a BNC connector, a variable resistor which is used for the calibration which I will explain during the testing, and a PH2.0 sensor interface circuit. This pH sensor kit is best for measuring water quality and other parameters. This pH sensor kit can be used in water quality monitoring equipment, it can be used in the water tanks, Fish aquarium, this pH Sensor kit can be used with GSM, nodemcu esp8266 wifi module for remote notifications. I personally recommend you should definitely visit.

They create innovative, user-friendly hardware & software products that become the building blocks in all kinds of electronic projects. This is the analog pH sensor kit from the DFrobot, DFrobot is a leading robotics and open source hardware provider. A pH meter takes advantage of this and works like a voltmeter: it measures the voltage (electrical potential) produced by the solution whose acidity we’re interested in, compares it with the voltage of a known solution, and uses the difference in voltage (the “potential difference”) between them to deduce the difference in pH…. In other words, it’s a bit like a battery that can produce a greater voltage. How does it do it?Īn acidic solution has far more positively charged hydrogen ions in it than an alkaline one, so it has greater potential to produce an electric current in a certain situation.

The basic idea is that the paper turns a slightly different color in solutions between pH 1 and 14 and, by comparing your paper to a color chart, you can simply read off the acidity or alkalinity without worrying how many hydrogen ions there are.īut a pH meter somehow has to measure the concentration of hydrogen ions. You can check manually the pH values of different liquids. If you’re using litmus paper, and you are not interested in any automatic system, or any notification system then none of this matters. A pH less than 7 is said to be acidic and solutions with a pH greater than 7 are basic or alkaline.” The total pH scale ranges from 1 to 14, with 7 considered to be neutral. “pH stands for power of hydrogen, which is a measurement of the hydrogen ion concentration in the body. Let’s first start with the very basic questions What is pH? And how a pH sensor actually works? I would appreciate your support in this way! I may make a commission if you buy the components through these links.

Gravity: Analog pH Sensor / Meter Kit For Arduino by DFrobot: Basic programming to find the pH value of different liquids and finally.As this is a getting started tutorial, so in this tutorial, we will only cover the extreme basics like for example
