TR-HTS FDR 4-20mA Output rs485 modbus i2c htc505 ip66 soil moisture and temperature sensor integrated temperature and humidity sensor has stable performance and high sensitivity. It is an important tool for observing and studying the occurrence, evolution, improvement and dynamics of soil. Soil temperature and soil moisture can be measured simultaneously; by measuring the dielectric constant of the soil, the true moisture content of various soils can be directly and stably reflected. The soil moisture sensor measures the volume percentage of soil moisture and is a soil moisture measurement method that meets current international standards.

Red(V+): +
Black(G): ground Blue(O1): Do not connect Brown(O2): Do not connect Yellow(T+): RS485+/A/T+ White (T-): RS485-/B/T- Green (SET): When connecting V+(power is positive), the power on start module enters "setting mode". When not connected or connected to G (power ground), the power start enters "operation mode". The configuration parameters such as Modbus address, baud rate, verification bit, communication protocol, etc. are stored in the EEPROM (power-off storage device) inside the module. Sometimes you forget the specific configuration of these parameters and cannot communicate with the module. To prevent this problem, the module has a special mode called setup mode. When the module starts up in Settings mode, the module will communicate with the following parameters: Modbus address is fixed at 0 Communication configuration is 9600,N,8,1(9600bps,no verification bit,8 data bits,1 stop bit) Communication protocol is Modbus-RTU Configuration parameters in an EEPROM do not change as the module enters "setup mode," and when the module is in "run mode," these configuration parameters in the EEPROM are still communicated. |
