The Soil pH Sensor is a valuable tool for measuring the acidity or alkalinity of soil, essential for optimizing plant growth. This sensor detects the pH level in soil and provides real-time readings, typically ranging from 0 to 14, where 7 is neutral, below 7 indicates acidic soil, and above 7 indicates alkaline soil. The sensor is designed for use in agriculture, gardening, and hydroponics to ensure plants receive the appropriate nutrients for healthy growth. It is commonly used with microcontrollers like Arduino or Raspberry Pi for automated soil monitoring systems. With easy integration and accurate readings, it helps gardeners and farmers maintain optimal soil conditions for their crops.
