Soil-Probe-3M-R-USB - Ubibot Soil-Probe-3M-R-USB Soil Temperature and Moisture Probe for WS1 Pro 3 Metres
Features
Ubibot Soil Temperature and Moisture Probe for WS1 Pro 3 Metres - Micro USB Connector
This product adopts modbus-rtu protocol, and the computer can monitor the temperature through the communication mode of RS485 interface. Cooperate with WS1 Pro series product to monitor the data on computer platform or mobile APP, and generate soil moisture and temperature report through the platform. The soil temperature and moisture sensor measures soil moisture content based on frequency domain reflection method. We think of the soil as a capacitance containing a medium, according to transmission line theory, the circuit due to the load impedance mismatch appear under a certain frequency resonant migration, reflection amplitude value is not the same at the same time, through comparing the difference of reflection wave and the incident wave amplitude value, measure the capacitance of the multiple reflection wave caused by the changes, and then measure the soil moisture content. The probe shell is made of ABS, which has good resistance to acid and alkali corrosion. The shell is completely wrapped and can reach the IP68 waterproof level, which means that the probe can be continuously measured in water.
- High precision, wide range, good consistency.
- Super stability and anti-interference.
- Wide voltage input,DC5-12V.
- Standard MODBUS RTU protocol.
1. All communication circuits shall follow the master/slave mode. In this way, data can be transferred between one primary station (e.g., PC) and multiple sub-stations. Any communication cannot start from a slave.
2. The information transmission mode is asynchronous, byte format is 1 start bit, 8 data bits, and 1 stop bit, no check.
3. Compliance with MODUBS RTU protocol standards.
4. The default baud rate is 9600 and the address is 0xC2.
Cooperate with WS1 Pro to achieve remote monitoring, report generation and other functions.

RS485 Interface

Widely used in homes, offices, farms and other places where soil temperature and moistureneedtobe measured.
