Two nonconductive liquids produce a conductive film where they meet, enabling 3D-printed all-liquid wires that obey Ohm's law ...

Abstract: Background: Accurate pH measurement is vital in diverse settings such as water quality assessment, food production, and laboratory procedures. This study introduces a pH meter design ...

The new 500 X pH/ORP sensor lasts up to 10 times longer than competing sensors in the harshest industrial applications, ...

In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

The Arduino is a great way for hobbyists and pros alike to experiment with programmable objects, but it can be confusing for beginners without these tools.

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Water pH is a critical parameter that determines the acidity or alkalinity of water. Measured on a scale from 0 to 14, pH levels influence chemical reactions, biological processes, and overall water ...

The pH is a measure of acidity or basicity in a solution and influences the activity of almost all enzymes and biochemical reactions. The cell is divided into compartments to allow specific biological ...

Although it dates back to the early days of the Marconi Company in the 1920s, the Franklin oscillator has remained a relatively obscure circuit, its memory mostly kept alive by ham radio operators ...

Abstract: The use of ruthenium oxide (RuO2) as a pH sensor is a relatively novel idea and understanding how preparation of the sensor effects and its sensing properties is crucial. In this article, ...
