USB Soil Sensor for Measuring Temperature, Humidity, pH & NPK

All-in-One Soil Monitoring: Measures soil temperature, humidity, pH, electrical conductivity, and NPK (nitrogen, phosphorus, potassium) nutrients in a single USB-connected device for comprehensive field or garden analysis. Lab-Grade Accuracy: Delivers consistent, repeatable readings using calibrated sensing elements-perfect for data-driven decisions in agriculture, horticulture, and home gardening. Robust Build: Features an IP68-rated stainless steel probe sealed with flame retardant epoxy resin to withstand prolonged soil contact, moisture, and temperature extremes from -40°C to 80°C. Plug-and-Play USB Operation: Requires no batteries-powers directly via USB connection to compatible devices; stores measurement history internally for later review and tracking. Multiple Configuration Options: Choose model A, B, C, or D based on your monitoring needs-each supports distinct parameter combinations including conductivity, temperature and humidity, pH, and NPK memory storage.
