1. It consists of a single integrated system for sensing, data acquisition and transmission, and power supply and charging, making it simple in structure and easy to install.
2. Made of high-strength PVC industrial plastic pipe with a diameter of 40mm, and internally encapsulated with epoxy resin, the entire machine can be submerged in water.
3. A layered point structure is adopted, with a soil temperature and humidity detection point set at a default interval of 10cm to observe the soil conditions within the corresponding range. The measurement area is within a cylindrical area with a diameter of 10cm surrounding the sensor.
4. The default height is 4 layers, with a total length of 660mm. Different height detection structures can be customized according to requirements.
5. Detection principle:
Soil moisture: Using FDR (Frequency Domain Reflectometry), the sensor emits high-frequency detection waves that can penetrate the outer tube, effectively sensing the surrounding environment. By measuring the dielectric constant of the surrounding environment, the volume percentage of environmental moisture is calculated.
Soil temperature: The real-time temperature at the corresponding detection point is displayed using a thermistor.
6. Communication transmission uses wired RS485 connection and Modbus RTU standard protocol.
7. Data can be configured for automatic reporting, and the reporting interval can be set .、
8. The number of layers can be customized, with a maximum of 9 layers and a minimum of 3 layers.
Suitable for soil moisture monitoring, scientific experiments, water saving irrigation, greenhouses, plant cultivation, grassland pasture, soil rapid testing, precision agriculture, etc.
