[Stephen]’s system uses commercially available sensors that track pH levels and Oxidation-Reduction Potential (ORP), both basic measurements that indicate water quality. A second set of sensors ...

Researchers at Northwestern University say the device could revolutionize how we monitor the health and recovery of ...

Called the Nectar Monitor, this pH meter is a more modern take on what is currently offered in this space. Open source and based on the ESP32, it’s accessible to most people with a soldering ...

To create a pH sensor they placed cytosine-rich DNA sequences on both ends of a piece of B-form DNA. When the pH drops, the ends come together and form an i-tetraplex. This DNA nanomachine ...

Maintaining proper pH levels is crucial for controlling microbial growth. Many harmful bacteria thrive in neutral pH ...

New bioluminescent sensors using engineered firefly luciferases provide accurate pH monitoring in living cells, enhancing ...

ISFETs allow the continuous and precise measurement of pH values by determining the concentration of certain ions in water or other aqueous media in real-time. Following the outstanding development of ...

Data from the sensors, which are sensitive to the changes in pH and temperature that can be caused by infections in crops, are collected by the electronic module. The data can be sent wirelessly ...

The University of Glasgow has created a pH sensor for soil testing that can be composted at the end of its life. It is an impedance-based sensor, using screen-printed interdigitated carbon-based ...

The electronics required to control the ion-sensitive field effect transistors (ISFET) have been successfully miniaturized. At the same time, manufacturing costs and power consumption have been ...
