[Sensor Sub-Component] Water Level Sensor Housing by McSquizzy

Last crawled date: 2 years, 12 months ago

This is a two-piece Thing: Top Tube and Bottom Tube.
This Thing combines with my Sharp GP2Y0A21 IR Sensor Housing and IR Sensor Puck to form an infrared water level measurement sensor.

The two pieces fit together in a friction / pressure fit. The cylinder is perforated to provide visual indication of the puck, water level, and any obstructing debris.

The top three threads are 4mm ANSI M Metric threads at 17mm deep, and join the IR Sensor Housing to the tube structure.
If I were to re-mix this part, I would remove the side perforations, and replace them with a vertical "window", either completely plastic-free, or with a transparent material. This would eliminate ripples in the body of water from affecting the puck and therefore the sensor reading, by extending the tube under the water's surface.
I might add an "intermediate" tube section, so users can extend the housing, up to 80cm long (Sharp's listed max distance for the IR sensor)
I will coat the part in an inert, non-toxic, Lac-based spray enamel to prevent the degradation of the ABS plastic in water.
