The 7-in-1 Soil Sensor for NPK, EC, pH, Temperature, and Humidity Detection is a multifunction soil monitoring device designed to provide real-time analysis of essential soil parameters. It integrates the measurement of nitrogen, phosphorus, potassium nutrients along with soil electrical conductivity, pH value, moisture level, and temperature in a single probe. The sensor is built with anti-corrosion stainless steel electrodes and a rugged waterproof enclosure, allowing long-term and stable operation in various soil conditions. It is widely used in agriculture, horticulture, greenhouse management, and smart irrigation systems to support precision farming and soil health assessment.
