Introduction: Soil Moisture Sensor Case
The soil moisture sensor is widely used to optimize plant irrigation and avoid water waste.
The very good sensors that you can find at a good price in online stores, like Sparkfun SEN-13322 that I used in my Green Detect project, usually come bare, without a water or dust protection.
Considering that these sensors are very often installed outdoors, I thought of designing a special open source case to be printed in 3D.
This project is for Sparkfun sensor, if you use other soil moisture sensors, you can edit the 3d file to fit your needs
I am happy to share this Instructable with you and I hope you find it useful!
Supplies
- SEN-13322 Sparkfun soil moisture sensor (for example: https://www.digikey.it/it/products/detail/sparkfun-electronics/SEN-13322/5764506)
- Soil Moisture Sensor Case (https://www.tinkercad.com/things/9VoWTwszHit )
- Cable gland PG9 (for example: https://www.amazon.it/gp/product/B07V9GK4R8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 )
- 3-pole cable
Step 1: Print Soil Moisture Case
Soil Moisture Case is composed by 2 parts: the box and the closing panel
Download the .stl attached files.
Print both parts
Step 2: Fix Cable and Gland to the Case Hole
Fix the cable gland and pass the cable that will connect to the sensor inside it
Step 3: Fix Soil Moisture Sensor
Slide the 2 sensor terminals through the 2 appropriate slots.
fix the sensor with 2 small self-tapping screws
Step 4: Connect the Sensor
Connect the wires to the sensor.
I suggest you to improve the fastening of the connection with hot glue
Step 5: Close the Case
Fix the cover with 4 small self-tapping screws
Step 6: Ready to Use!
