Rain Gauge w/ Hall Effect Sensor

cults3d

Work In Progress: Changes Coming Soon Note that all STLs are randomly oriented, not in the suggested print orientation. When I finalize the design, I will orient them correctly in the final revision. Experimental Rain Gauge for Arduino Weather Station https://www.thingiverse.com/SeanTheITGuy/collections/arduino-weather-station This simple tipper-based rain gauge is still a work in progress and may need some adjustments. Hall Effect Sensor 5x2 Magnets Data Collection The rain gauge collects data by gathering rain in the funnel, which has a collection surface area of 78.54 cm^2. I have not yet calibrated the tipper to determine how much water it takes to trigger a tip, but this information will be available as I gather more components and add programming. Assembly Instructions Attach the tipper to the base using M3 screws that fit snugly into the tipper and loosely in the base. These screws act as pivot points and should minimize friction on the tipper body. Sensor Activation A 5x2mm neodymium magnet is glued into the tipper to balance its weight, and when the tipper tips, this magnet moves past a naked Hall effect sensor glued into place. The three wires from the sensor can be soldered or connected with Dupont wires, then passed through the cylinder wall and into the main control box. Assembly Tips When threading the bracket into the cylinder, ensure it is snugly in place and as close to vertical as possible for accuracy. If the threads don't align properly, apply some CA glue to secure the bracket firmly. The funnel and base should be glued into the cylinder, with the option to add screw fasteners in the future.
