RS485 soil moisture sensor

RS485 Soil Moisture Sensor Product Description:

In the field of agricultural production and environmental monitoring, accurately grasping the soil moisture and temperature conditions is the key to improving crop yields, optimising irrigation strategies and protecting the ecological environment. With the progress of science and technology, RS485 Soil Moisture Sensor comes into being, with its high accuracy, high sensitivity and stable performance, it becomes an indispensable tool for modern agriculture and environmental monitoring.

In this paper, we will discuss the technical principles, characteristic advantages and application scenarios of RS485 soil temperature and moisture sensors, and show its important role in smart agriculture. In the field of modern agriculture and environmental protection, accurate monitoring of soil moisture and temperature is crucial.

RS485 Soil Moisture Sensor Working Principle.

The RS485 Soil Temperature and Moisture Sensor uses advanced electromagnetic wave pulse technology to transmit signals through a coaxial cable to a probe that penetrates deep into the soil. As these electromagnetic pulses propagate through the soil medium, they are affected by the soil's moisture content, which changes their reflection or transmission characteristics. The sensor uses these changes to measure the apparent dielectric constant of the soil, a parameter that is closely related to the true moisture content of the soil. Through complex algorithmic processing, the sensor is able to accurately calculate the soil moisture value, while the integrated temperature sensor is responsible for monitoring the soil temperature, realising an integrated temperature and moisture measurement and providing comprehensive information on the soil condition for agricultural production.

RS485 Soil Moisture Sensor Product Features

- TDR Measurement: The sensor adopts advanced electromagnetic wave pulse technology, which can accurately measure the moisture and temperature of the soil and provide scientific basis for agricultural production.

- Strong stability: unique probe design and high quality materials ensure the sensor's long-term stable operation in complex soil environments.

- Anti-interference ability: the sensor is not affected by fertiliser and metal ions in the soil, which ensures the reliability of the measurement data.

- Multiple output forms: In addition to the RS485 digital communication interface, it also provides two types of analogue signal outputs: current 4-20mA and voltage 0-5V, which meets the interface requirements of different users and facilitates seamless connection with various data acquisition systems, PLC controllers or monitoring software.

- Low power consumption design: The product power consumption is as low as about 0.3W, which reduces energy consumption, prolongs the service life of the equipment in the field environment, and reduces maintenance costs.

- High accuracy and sensitivity: RS485 soil temperature and moisture sensor is able to achieve a wide range of soil moisture measurement from 0 to 100%, and the resolution is as high as 0.1%, which ensures the fineness of the data. The temperature measurement range covers -50~100℃ with the same high resolution of 0.1℃, which meets the monitoring needs in many extreme environments.

- Wide operating environment and high protection level: it can work normally under the extreme temperature of -40℃~80℃, and at the same time, it achieves the waterproof and dustproof level of IP68, so it is fearless of the harsh environment, and is suitable for all kinds of outdoor and underground monitoring scenarios.

- Wide range of applications: Suitable for a variety of soil types and environments to meet different monitoring needs.
