"The 2D nature of the host material also opens exciting new possibilities for using this sensor. For example, the spatial resolution for this technique is determined by the distance between the ...

An international team of researchers has successfully controlled the flow of energy in a molecule with the help of its pH value ... to the development of new sensors for medical diagnostics ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

If you want to know the acidity (or alkalinity) level of your pool or aquarium water, you need a pH meter. In this article, we present a pH meter that can accurately measure the pH value of a solution ...

allowing you to effortlessly integrate it into your Arduino projects. The PH4502C sensor is a high-precision pH sensor capable of accurately measuring pH levels in various applications. Simple and ...

[David] had exactly this problem with a pH sensor, and rather than buy an expensive module to do the job he designed his own. The sensor in question produces a relatively tiny voltage of -0.414 to ...

An SMU graduate student has developed a miniature pH sensor that can tell when food has spoiled in real time. DALLAS (SMU) – Forget that expiration date on your salmon or yogurt. A graduate student at ...

It offers better accuracy than pH Indicator solutions and litmus tests. The sensor can easily be integrated with Raspberry Pi and Arduino, making it suitable for both the maker community which relies ...
