2" NPT cap for Maxbotix USB ultrasonic sensor (oil tank level readings)

cults3d

I found the Maxbotix ultrasonic sensors to be quite good for monitoring the level in our home heating oil tank, but up to this point I was buying a 2" NPT PVC pipe plug and swapping that into a blank spot in the top of the tank. This required careful drilling of the pipe plug, and the end result worked but didn't look good. This thing started out life as a a 3D model from McMaster-Carr, which I modified with provision for the Maxbotix USB sensor with a side port access for the USB cable. See "How I Designed This" below for more details. Previously, I've used the Maxbotix sensors with TTL serial output (MB1043) but they've since released a USB model which is far easier to work with, so I've customized this thing for use with the MB1443 USB sensor. Maxbotix has several tutorials on using their sensors with a Raspberry Pi: Older tutorial for serial sensors: Interfacing a Raspberry Pi with an ultrasonic sensor More current tutorial for USB sensors: Connect a Raspberry Pi Zero with an USB Ultrasonic Sensor Here's a video showing a time lapse of my data compared to the actual physical float level on the oil tank showing how well it matches up: https://www.youtube.com/watch?v=5Ic_27f4kBo
