Soil NPK Sensor
Helps develop data-driven fertilization strategies by accurately measuring the levels of Nitrogen (N), Phosphorus (P), and Potassium (K) in agricultural soils. The measured data is transmitted to IoT platforms via LoRaWAN technology and can be monitored remotely. Thanks to its durable IP67 waterproof probe, the sensor can be embedded directly into the soil and operate reliably for long periods. The device is battery-powered and very easy to install; once the probe is placed, the data collection process starts automatically.
By default, the sensor sends data every 15 minutes, and this interval can be adjusted according to specific needs through the IoT interface. On the ZenoSmart platform, data can be tracked in daily, weekly, or monthly reports. It ensures timely and accurate fertilization, preventing over- or under-fertilization, protecting soil quality, and reducing the risk of environmental pollution. In this way, plant growth and crop quality are maximized.
