NodeMCU Water Level Sensor Enclosure
Description
I am working on a water tank level sensor using a Nodemcu V3 micro controller. This is not a tutorial on how to create a water level sensor, its a standard demo project with lots of resources on you-tube among other sites. The parts listed are what this version of the enclosure is designed to house, that is all. This is a work in progress. The sensor is being designed to be standalone with wireless connectivity for remote monitoring. The unit is powered by 2x 18650 batteries, it runs for approximately 48hrs without charging, eventually when the new 5v UPS boards arrive, the batteries will be charged of a 12v 10w solar panel. The mounting bracket slots into my Weifeng camera tripod while developing, but can be drilled to mount on a pole with U bolts or screwed to a wall etc. Screw holes are M 2 self taping, you can drill them out to suit your screws. The PCB rail is glued to the battery housing. The mounting bracket and base plate are designed to clamp a o-ring around the sensors to further waterproof the enclosure, not important as this is a prototype. I have not designed a cover for it until I get an external antenna that will be incorporated into the cover. Parts: Nodemcu V3 HC-SR04 ultrasonic sensor 5V 2A Solar Panel Fold Bag USB Junction Box, this will be replaced with > 5V UPS Power Diy Board Charger & Step-up DC DC Converter Module 3.7V Li-ion LiPo .
