TR-HTSE RS485 RS232 Water Content VWC Combined
Soil Temperature Humidity EC Sensor

Product Description

 

TR-HTSE RS485 RS232 Water Content VWC Combined Soil Temperature Humidity
EC Sensor has high stability and sensitivity, it is an important tool to observe and study
the occurrence, evolution, improvement and water&salt dynamics of soil. By measuring
the dielectric constant of soil, we can directly and stably reflect the real moisture content
of all kinds of soil. TR-HTSE soil moisture sensor, which can measure the volume
percentage of soil moisture, the method is accordance with the current international
standards. It is suitable for soil moisture monitoring, scientific experiment, water-saving
irrigation, greenhouse shed, flowers and vegetables, grassland pasture, soil rapid
measurement, plant culture, sewage treatment, precision agriculture and so on.

 

The Soil Temperature Humidity EC Sensor has the following characteristics:
(1)Soil moisture content, electrical conductivity and temperature in one.

(2)It can also be used in water and fertilizer solution, as well as in the conductivity of
other nutrient solution and substrate.

(3)The electrode adopts the special treatment alloy material, can withstand the strong
external force impact, is not easy to damage.

(4)Completely sealed, resistant to acid and alkali corrosion, can be buried in soil or
directly into water for long-term dynamic detection.
(5) High precision, fast response and good interchangeability. The probe insertion
design ensures accurate measurement and reliable performance.

(6)Perfect protection circuit and various signal output interfaces are optional.

Wiring Method

 

Wiring:

Module configuration parameters such as Modbus address, baud rate, check bit, communication
protocol and so on are stored in the EEPROM (power-down storage device). Sometimes may
forget the configuration of these parameters and can't communicate with the module. To prevent
this problem, the module has a special pattern called "setting mode". When the module is powered
on, the module communicates with the following parameters:
1.Modbus address fixed to 0

2.Thecommunication configuration is 9600,N,8,1(9600bps, no check bit, 8 data bits, 1 stop bit)

3.Communication protocol is Modbus-RTU The configuration parameters in EEPROM do no
 change when the module enters "setting mode". When the module is in "operation mode" ,
it still communicates according to these configuration parameters in EEPROM.

Application Field

TR-HTSE RS485 RS232 Water Content VWC Combined Soil Temperature Humidity EC Sensor be
used in these fields:

1. Monitor soil moisture temperature ec(electricity conductivity) in agricultural greenhouses to control
irrigation systems.
2. Easy to observe whether the open farmland is short of water.
3. Monitor ground humidity and study the impact on the surrounding environment.
4. Collect soil moisture temperature ec(electricity conductivity) data needed for scientific research.
