 Multi-Layer Soil Moisture Sensor Technical Specifications 

 Installation and Deployment Recommendations 

To ensure representative and accurate data, careful selection of installation locations is essential. Below are key recommendations:

 1. Choose Representative Plots  

   Monitoring points should be located in areas with dominant crops and typical soil types, reflecting regional soil and planting conditions. Prioritize plots with the largest crop coverage and minimal soil or terrain variation. 

2. Terrain and Distance Requirements  

   - Place monitoring points ~20m from plot edges or roads, avoiding low-lying areas prone to water accumulation.  

   - Maintain a distance of >50m from ditches or water channels to prevent seepage-related measurement errors.  

   - In hilly areas, select plots >1 acre with gentle slopes, avoiding gully bottoms or steep inclines.  

   - In flat plains, choose plots >10 acres that are level and not prone to waterlogging. 

3. Stability and Continuity  

   Once selected, monitoring locations should remain fixed to ensure data consistency and comparability over time. 

4. Installation Steps  

   - Use specialized tools to vertically insert the sensor into the soil, ensuring monitoring nodes align with target depths.  

   - Connect power and signal lines, verifying anti-misconnection protection.
