A soil sensor is a device used to measure various properties of soil, such as moisture, temperature, and nutrient levels. These sensors help farmers and gardeners monitor soil conditions, ensuring optimal growth for plants. By providing real-time data, soil sensors can improve irrigation practices and reduce water waste. Soil sensors can be connected to smartphones or computers for easy data access and analysis. They are often used in precision agriculture, where technology is applied to enhance crop yields and sustainability. This technology supports better decision-making for land management and environmental conservation.
