Soil sensors are devices used to measure various properties of soil, such as moisture, temperature, and nutrient levels. These sensors help farmers and gardeners monitor soil conditions, allowing them to make informed decisions about irrigation and fertilization. By providing real-time data, soil sensors can improve crop yields and promote sustainable farming practices. Typically, soil sensors are placed in the ground and connected to a data collection system. Some advanced models can transmit information wirelessly to smartphones or computers, making it easier for users to track changes over time. This technology is increasingly popular in precision agriculture, where efficiency and resource management are crucial.
