thingiverse
Enclosure with PIR sensors mounted at a 120° angle between each other and sealed with a lid after sensor calibration. The enclosure features a slot for a strap and is curved to ensure secure attachment to a tree. Sensor outputs can be connected in parallel with additional diodes for enhanced functionality. A hole for a three-wire cable (power, ground, and output) must be drilled precisely where needed. It's essential to protect the internal electronics from moisture exposure. Printing specifications: First layer thickness is 0.24mm, while subsequent layers are 0.36mm thick, with a nozzle diameter of 0.50mm.
