The pH of the culture medium is a critical process parameter in cell culture bioprocesses. To successfully transfer processes between bioprocess systems and sites (i.e., in the course of process ...

This Arduino project reads pH values from a pH sensor and sends the data to the ThingSpeak IoT platform via Wi-Fi. The project utilizes an analog pH sensor connected to analog pin A0 and communicates ...

Like swimming pools, hot tubs need regular monitoring to ensure their water stays clean and clear. An average person might take a water quality reading once or twice a week using test strips, but such ...

Conductivity sensors can do more than just measure conductivity. Calculated values from the M800 Transmitter using conductivity data can provide valuable cycle chemistry information, confirm on-line ...

It’s rare in 2023 for an instrument to be entirely analog, instead it’s more normal for a front-end to feed the analog-to-digital converter (ADC) in a microcontroller. Typically the front-end will do ...

A graduate student at Southern Methodist University (SMU), has developed a miniature pH sensor that can detect when food has spoiled in real-time. The 2-millimeter long and 10-millimeter wide flexible ...

Abstract: A pH sensor based on the dispersion turning point (DTP) is proposed, with a structure involving a thin layer of calcium alginate hydrogel coated on a tapered single-mode fiber (SMF). The ...
