Soil water potential sensor is designed for precise soil moisture potential monitoring in agricultural and environmental applications. It operates on a 5–30 V DC power supply and provides stable RS485 (ModBus) output. SUCH soil sensor offers a measuring range of -5 to -100 kPa with 0.1 kPa resolution, supporting real-time data transmission and long-term field use. Its IP68-rated design ensures reliable performance in outdoor soil monitoring and irrigation management systems.
The wide voltage power supply supports an input range of 10–30V.
When connecting RS485 signal wires, ensure that the A and B lines are not reversed.For multiple devices on the same bus, make sure that their addresses do not conflict.
While a soil moisture sensor measures the volumetric water content, the soil water potential sensor measures the energy state of water in the soil. This makes it more suitable for evaluating plant water stress and optimizing irrigation timing.
Yes. It features an IP68-rated waterproof design, making it suitable for long-term outdoor use in agricultural fields, greenhouses, and research environments without damage from moisture or dust.
Yes. The sensor’s RS485 ModBus output allows integration with smart irrigation controllers, enabling automatic adjustment of irrigation cycles based on soil water potential readings.
