DeepL Five Pin Soil Four Parameter Sensor User Manual

Overview

The five-pin soil four-parameter sensor is a stable performance with high sensitivity, fast response and stable output for a variety of soils. It is an important tool for observing and studying the occurrence, evolution and improvement of saline soils as well as water and salt dynamics. By measuring the dielectric constant of the soll, it can directly and stably reflect the true moisture content of various soils. It can measure the volume percentage of soil moisture, and is a soil moisture measurement method that meets current international standards. It can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistant, vacuum potting, and completely waterproof.

Features

1. This sensor is designed for compact size.
2. High measurement accuracy, fast response time and good interchangeability.
3. Good sealing, can be directly buried in the soil and used without corrosion.
4. The soil quality is less affected and the application area

How to use

The equipment can be connected to a variety of data collectors containing differential inputs, data acquisition cards, remote data acquisition modules and other equipment with the following wiring instructions:

Data conversion method

RS485 signal (default address 01):

Standard Modbus-RTU protocol, baud rate: 4800; parity bits: none; data bits: 8; stop bits: 1

Change of address

For example: change the sensor with address 1 to address 2, host — slave

Original l address s| Function n Code| Starting Mail Storage High| Starting Mail Memory low| Start Address High| Start Address Low| CRC16Low| CRC16High
---|---|---|---|---|---|---|---
0X01| 0X06| 0X07| 0XD0| 0X00| 0X02| 0X08| 0X86

If the sensor receives correctly, the data is returned in the original way.

Note: If you forget the original address of the sensor, you can use the broadcast address 0XFF instead. When using OXFF, the host can only receive one slave, and the return address is still the original address, which can be used as a method of address query.

• Temperature calculation:
• Temperature data is uploaded in the form of a complementary code when the temperature is below 0 °C. Temperature: FF9B H(hex) = -101 =>
• Temperature = -10.1 °C Moisture Calculation:
• Moisture: 292 H (hexadecimal) = 658 => Moisture = 65.8%, i.e. 65.8% water content by volume of the soil. Conductivity calculation:
• Conductivity: 3E8 H (hexadecimal) = 1000 Conductivity = 1000 uslem PH Value Calculation:
• PH value: 38H (hex) = 56 => PH value =5.6

Precautions for use

Waming

• Failure to wire in accordance with the wire sequence may result in damage to the device and to the instrument connected to the device.
• If the input power exceeds the maximum access power of this device, it will cause damage to this device.

Note

Please read this manual completely before use.

Do not attempt to insert the probe into stones or hard soil clods as this may damage the probe. A When moving the sensor out of the soil, do not tug and pull the cable directly.

The sensor probe should be inserted into the soil/substrate sufficiently to reduce operational errors and improve measurement accuracy.

It should be calibrated before each measurement, and for long-term use itis recommended to calibrate once every 1 month. The calibration frequency should be adjusted according to different application conditions (soil quality, moisture content, salt content, acidity and alkalinity of the application, etc.).
