Learn how to create a simple heart rate monitor using an Arduino Pro Mini, PulseSensor, and OLED display. This ...

Water pH measurement is vital as it provides fundamental information about its quality and suitability for agriculture, aquatic ecosystems, industry, and human consumption. Each of these applications ...

Here we report on a bioresorbable fluorescence sensor for in vivo pH monitoring. The sensor leverages a nanometer-thick multilayer stack of polyelectrolytes labelled with a pH-insensitive fluorophore ...

Gesture-based home automation allows users to control household devices through simple hand movements, removing the need for switches or remotes. It improves convenience, accessibility, and hygiene ...

To develop in vivo monitoring meter for pH measurements is still the bottleneck for understanding the role of pH plays in the brain diseases. In this work, a selective and sensitive electrochemical pH ...
