IP68 TRANSDUCE HUMIDITY SELF-SENSOR

Features:

1. Product composition: The soil moisture sensor is composed of a power supply module, a transmission module, a zero drift and temperature compensation module, and a data processing module.
2. Powerful function: The sensor integrates signal sampling and amplification, zero drift and temperature compensation functions, which have little impact on soil quality and are widely used in a wide range of fields.
3. 0-100% measuring range: high measurement accuracy, reliable performance, fast response, good interchangeability and high data transmission efficiency.
4. Compact Design: This soil moisture sensor has a small and lightweight appearance, easy to carry and connect. The cable length is about 1.5 meters, which can meet the usage needs.
5.Durable Use: Supports constant dielectric signal output, good sealing, IP68 protection level, can be directly buried in the ground and used, not easy to corrode or rust.

RS485 Positive Power Negative Power 485A 485B Example read command format: 02 03 00 00 00 01 84 39
Note: The first byte 02 is the station number.If you have changed the station number setting, you must replace the first digit 02 with the station number you have set.The last two digits, 84 39, are CRC16 checksums and clients must calculate them themselves.
Example of the returned data command format: 02 03 02 01 1F BC 1C
Note: Bits 4 and 5 of 01 1F are the moisture value, and BC 1C is the returned CRC checksum.
Method for analyzing soil moisture data: Moisture = 0 x 011F / 10 = 28.7%
Change your own station number:
Method 1: Know the current station number and send the following command:
02 10 10 00 00 01 02 00 03 E3 60 Its function is to change the station number from #2 to #3.
Note: Replace the italicized characters with the number of Enter the source station and replace the normal characters with the value of the target station number you wish to change.Sending requires the client to calculate the CRC value by itself.
Method 2: Know the current station number and send the following command
02 06 10 00 00 03 CD 38 Its function is to change the station number of No. 2 to #3.
Note: Replace the italicized characters with the original station number and replace the regular characters with the value of the target station number you want to change. Sending requires the customer to calculate the CRC value by themselves.
Method 3: Forget the original station number, you need to connect the product to the computer alone, pay attention
There can be no other 485 products on the bus. Use station 0 to operate them. The instructions are as follows: 00 10 10 00 00 01 02 00 03 FA 00
Note: The large letters are the value of the target station number you wish to modify.The customer calculates the CRC control value themselves.
This sensor uses the FDR (frequency domain) method to measure soil moisture, which can correspond to the volumetric moisture content of the soil.The FDR (frequency domain) method for measuring soil moisture is mainly related to the pH of the measured soil, soil density, soil quality, and measurement depth.
Fault analysis and elimination:
1.The sensor output signal is abnormal.
Check if the supply voltage is stable.
Check if the supply range is normal.
Check if the line is virtual.
2.The sensor has no signal output
Check whether the positive and negative poles of the power supply and the ground wire are correctly connected
Check whether the power supply voltage meets the requirements
Care and maintenance:
This The instrument is a scientific and technological product with excellent design and functional principles, and special attention should be paid to maintenance. The following suggestions will help you use maintenance services effectively.
1. Prevent the instrument from being scratched, maintain the integrity of the external protection

Package List:

Package Including: 1 x Soil Moisture Sensor
1 x English Manual

Note:

1. Please allow 0-1 inch error due to manual measurement. Thank you for your understanding.2.Monitors are not calibrated the same way; the color of the item shown in the photos may be slightly different from the actual object.Please consider the actual product as the standard.Before measuring, a soil sample of uniform density must be selected as the object to be measured.Do not insert the sensor probe into the hard soil block to avoid damaging the probe.Do not pull directly on the cable to move the sensor out of the soil. Hold the soil sample in the outer epoxy packaging with your hand.After use, use a brush to remove dust from the probe and dry it with a soft cloth to protect it from moisture and increase its lifespan.
