An Arduino Uno pH sensor measures the acidity or alkalinity of a solution by detecting hydrogen ion concentration. It's commonly used in hydroponics, aquariums, and environmental monitoring for pH ...

The pH meter project features open software and open hardware design circuit which can be connected with an electrode pH sensor made of glass. The device is termed as pHduino which can operate by ...

Abstract: Unplanned use of fertilizers leads to inferior quality of crops. Excess of one nutrient can make it difficult for the plant to absorb the other nutrients. To deal with this problem, the ...

Abstract: This paper proposes an automatic system that treats the household waste water to obtain optimum pH which is suitable for crop irrigation. Each plant species has a preferred pH and in general ...

Will not be affected by the type of liquid. Can detect the liquid level of boiling water Strong compatibility penetrates all kinds of non-metallic containers or pipes such as plastic, glass, ceramic, ...

In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and WiFi — are all ...
