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 base setup for this system is located in a room with approximate dimensions of 9.29 square metre. The room is non-air conditioned and does not receive any direct sunlight. The proposed setup aims ...

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 ...

Our Smart Home Using Arduino Uno R4 WiFi project is designed for home safety and convenience, integrating temperature, humidity, light, and gas monitoring. Using sensors like DHT11/DHT22, LDR, and ...

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 ...
