Outdoor Enclosure - SmartThings multipurpose sensor V2

thingiverse

Outdoor gate sensors are hard to come by and expensive for the SmartThings ecosystem. A lot of people in the community attempt to waterproof the excellent ST Multipurpose sensor to meet their needs. This enclosure is made to be printed in a way to fully encapsulate the sensor portion of the device to make it weather resistant. To test it I submerged it in water for 8 hours to see if it would leak and it held up great. Here are the printing instructions. 1. Load the STL into your slicer (I used Cura) 2. Force the print to pause at layer 113. (In Cura Go to extensions, post processing, modify G-code, choose "Pause at height", change pause at to "Layer No." and "Pause Layer" to 113) 3. When the print pauses slide the electronic (Fatter) portion of the sensor into the print with the flat side facing up. (the sensor itself will act as the support for the cap) 4. Resume Print 5. When complete inspect the print for proper layer adhesion and make sure you don't have any cracks that could let moisture in. 6. When you need to replace the batteries simply crack open the shell, change the battery, and print a new case I made this for myself to fill a need and am sharing it because I thought others would find it useful. The box should fit perfectly to the V2 sensor (the one with the rounded corners in the pictures) I used PLA but there are other materials that are more weather resistant. Some people will say a sealed box will degrade the battery performance or not let heat dissipate and reduce the life of your sensor. For me I only paid $18 for the sensor and haven't seen any adverse effects but your mileage may vary. This sensor is getting attached with adhesives but I will add one with ears for screws and slots for zip ties in the near future.
