Ground sensors are devices designed to detect and monitor various environmental conditions or activities on the Earth's surface. They can measure factors such as temperature, humidity, soil moisture, and even movement. These sensors are often used in agriculture, environmental monitoring, and security applications to gather real-time data. These sensors can be connected to a network, allowing for remote monitoring and data analysis. They play a crucial role in smart farming, where farmers use the information to optimize crop growth and resource use. Additionally, ground sensors are essential in military operations for surveillance and reconnaissance purposes.
