irrigation sensors for soil moisture

Introduction to NBL-S-THR Soil Moisture and Temperature Sensor

The NBL-S-THR Soil Moisture and Temperature Sensor(irrigation sensors for soil moisture) is a high-precision, highly sensitive instrument for measuring soil moisture and temperature. Utilizing electromagnetic pulse technology, it emits electromagnetic waves through a probe to measure the soil's apparent dielectric constant, accurately calculating true moisture content while monitoring soil temperature. The sensor offers rapid, accurate, and reliable performance, unaffected by fertilizers or metal ions in the soil. With an IP68 protection rating and robust design, it ensures long-term operation in harsh environments, making it ideal for soil moisture monitoring, water-saving irrigation, greenhouses, pastures, and rapid soil testing.
