The next discussed sensor, which could also be the last, measures the oxidation reduction potential (ORP) of a liquid. ORP is a value that indicates, in this case, how well water can oxidize or reduce another substance [1]. If the value is positive, the water is an oxidizing agent, if the value is negative it’sContinue reading “[SENSORS] Oxidation Reduction Potential – 24/05/2021”

Temperature can seem like a simple water property. However, it affects almost every other property. It’s one of the most important characteristics to measure, because temperature can explain trends or anomalies in the other retrieved data. The illustration on the left shows how the different water properties affect each other [1]. We can clearly seeContinue reading “[SENSORS] Temperature – 23/05/2021”

Another useful property of a liquid for water monitoring is turbidity. The analog turbidity sensor can determine the quality of water by sending and retrieving a beam of light. This beam will be scattered in multiple directions by suspended particles in the water. These particles are referred to as total suspended solids (TSS) [1]. YouContinue reading “[SENSORS] Turbidity – 22/05/2021”

The second sensor covered in these posts is the analog electrical conductivity (EC) sensor. It has a very similar usage to the pH sensor, both being analog and accompanied by buffer solutions. The EC sensor will be used to measure the electrical conductivity of a body of water. EC is an important characteristic in waterContinue reading “[SENSORS] Electrical Conductivity – 21/05/2021”

The first sensors that come to mind when wanting to monitor the quality of water are for its temperature and pH. This post will cover the latter, the pH sensor. Seeing as H2OSupport will be operated by an Arduino microcontroller, there’s only so much it can do. Microcontrollers can send and receive electronic signals. Therefore,Continue reading “[SENSORS] Acidity – 20/05/2021”
