RS485 Soil Temperature and Humidity Sensor
High-Precision Frequency Domain Soil Moisture Sensor
The soil moisture sensor adopts high-frequency electronic technology based on the principle of frequency domain reflection. By measuring the soil dielectric constant, it can accurately and stably reflect the true volumetric moisture content of various soils. Currently, this is the most internationally popular soil moisture measurement method. The sensor integrates a power module, temperature sensing module, transmission module, temperature compensation module, and data processing module, ensuring strong environmental adaptability and reliable performance in diverse application scenarios.
Technical Features of Soil Temperature and Humidity Sensor:
(1) Compact and reasonable structure design.
(2) High measurement accuracy, fast response and good interchangeability.
(3) Excellent sealing performance with IP68 waterproof rating, can be directly buried in soil and resist corrosion.
(4) Less affected by soil types, widely applicable in various regions.
(5) Stable and accurate measurement, reliable performance and high data transmission efficiency.
