NodeMCU Water Level Sensor Enclosure

thingiverse

I am designing a water tank level sensor using a Nodemcu V3 micro controller. This is not a tutorial on how to create a water level sensor, but rather a standard demo project with plenty of resources available online. The parts listed are the specific components that this version of the enclosure is designed to house. This is an ongoing project. The sensor is being developed as a standalone unit with wireless connectivity for remote monitoring. The unit is powered by two 18650 batteries, allowing it to run for approximately 48 hours without recharging. Once new 5V UPS boards arrive, the batteries will be charged using a 12V 10W solar panel. The mounting bracket slots into my Weifeng camera tripod while I am developing it, but can be drilled to mount on a pole with U bolts or screwed to a wall etc. Screw holes are M2 self-tapping, which can be drilled out to suit your screws. The PCB rail is glued to the battery housing. The mounting bracket and base plate are designed to clamp an O-ring around the sensors to further waterproof the enclosure. However, this feature is not essential for now as it is a prototype. I have yet to design a cover for it until I get an external antenna that will be incorporated into the cover.
