HS28N01-TR3 Soil Moisture and Temperature Profile Probe

Reference
HS28N01-TR3

The multi-segment soil moisture and temperature profiling probe is a sensor based on the principle of dielectric constant. It dynamically observes soil moisture content and temperature at different levels: this model measures the temperature and moisture of 3 soil segments (5 segments at most).

The probe uses standard Modbus-RTU485 communication, with a range of up to 2000 meters. Its PVC plastic tube shell lets the high-frequency detection wave of nearly 1 GHz pass through and is not affected by salt ions in the soil.

Overview

Features

  • The shell is made of PVC plastic tube. The probe emits a high-frequency detection wave of nearly 1 GHz that passes through the plastic tube and effectively senses the soil environment.
  • Not affected by salt ions in the soil: agricultural activities such as fertilizers, pesticides and irrigation do not affect the measurement results, and the data is accurate.

Technical parameters

  • Operating temperature: -40℃ – 80℃
  • Measuring range: soil moisture 0 – 100%; soil temperature -30℃~60℃
  • Measurement accuracy: soil moisture ±5%; soil temperature ±0.5℃
  • Measuring point spacing: 10cm
  • Power supply: 10-30VDC
  • Shell material: PVC plastic pipe
  • Protection level: IP68
  • Output signal: RS485 (Modbus protocol)
