Soil Temperature + Humidity RS485 Output Sensor with 2M Cable 3 pin Probes

Soil Temperature Humidity Sensor Probe RS485 Output 0-5V 0-10V 4-20mA Analog Soil Moisture Detector Sensors IP68 Protection

Overview

The sensor is stable in performance, high in sensitivity, fast in response and stable in output, suitable for all kinds of soils. It is an important tool to observe and study the occurrence, evolution, improvement and water-salt dynamics of saline soil. By measuring the dielectric constant of soil, it can directly and stably reflect the real moisture content of various soils. The volume percentage of soil moisture that can be measured is a method of measuring soil moisture according to the present international standard. Can be buried in the soil for a long time, resistance to long-term electrolysis, corrosion resistance, vacuum sealing, completely waterproof.

Features

(1) compact design of the sensor.

(2) high precision, fast response and good interchangeability.

(3) good sealing, can be directly buried in the soil for use, and not subject to corrosion.

(4) the influence of soil quality is small and the application area is wide.

(5) accurate measurement, reliable performance, ensure normal work, high data transmission efficiency.

Scope of application

Suitable for soil moisture monitoring, scientific experiment, water-saving irrigation, greenhouse, flowers and vegetables, grassland and pasture, soil rapid measurement, plant culture, sewage treatment, precision agriculture and other occasions of temperature and humidity, conductivity, PH test.
