Soil Multi-Parameter Sensor

The Soil Multi-Parameter Sensor (7-in-1) is designed for precision agriculture, smart farming, hydroponics, and greenhouse automation. This versatile sensor monitors multiple soil parameters simultaneously, including pH, EC (salinity), soil moisture, temperature, and NPK levels, enabling farmers, researchers, and hobbyists to optimize soil health and plant growth.

With real-time readings, this module helps maintain the perfect environment for crops, prevent over-fertilization, and improve yield. Its compatibility with Arduino, ESP32, NodeMcu, and Raspberry Pi allows integration into IoT and smart farming dashboards for automatic irrigation, fertilization, and environmental monitoring.
