ZONEWU LoRaWAN four in one sensor designed specifically for precision agriculture integrates soil moisture, temperature, pH, and conductivity monitoring. It can penetrate deep into the soil layer and accurately detect key parameters such as temperature, humidity, conductivity, and pH in real-time, with minimal measurement errors. By adopting LoRaWAN remote low-power communication technology, stable transmission and low energy consumption can be achieved even in remote farmland. With the help of supporting software, farmers can grasp the soil nutrient status at any time. Scientific fertilization not only saves costs but also improves crop yield and quality, helping agriculture develop towards intelligence and efficiency.
