Precision Housing for Capacitive Soil Moisture Sensors

This enclosure provides a streamlined solution for protecting your smart gardening hardware. Specifically tailored for the Capacitive Soil Moisture Sensor (v2.0.0), this design eliminates the look of exposed PCBs in your planters while significantly extending the life of your electronics. 

Key Features & Design Benefits

• Zero-Support Printing: Optimized geometry allows for a clean print right off the build plate without the need for any support material or post-processing.
• Precision Snap-Fit: Features a secure, tool-less locking mechanism. The case halves click together firmly, removing the need for screws or external fasteners.
• Slim-Profile: The ultra-lean design ensures the sensor remains unobtrusive, fitting easily into small pots without disturbing root systems.
• Universal Wiring Access: The entry port is designed to accommodate a variety of setups, from standard multi-core cables to individual dupont connectors.

Material Recommendations

• Indoor Use: PLA is perfectly suitable for indoor environments and decorative plants.
• Outdoor/Greenhouse Use: For high-temperature or high-UV environments, we recommend PETG, ABS, or ASA to ensure the housing remains durable and warp-free over time.

Enhanced Durability & Weatherproofing

To maximize hardware reliability in damp soil, we recommend implementing additional environmental sealing. For a fully water-resistant build, the internal cavity can be filled with silicone or epoxy after the sensor is seated.

• Integrated Circuitry: Apply a conformal coating or sealant to the electronic components on the upper portion of the PCB.
• Lateral Edges: Seal the sides of the board to prevent moisture from wicking into the PCB layers.
• Recommended Sealants: High-grade epoxy resin, silicone sealant, or specialized water-resistant coatings.
