I love coffee and side projects. I wanted to solve a coffee related annoyance that I faced on a regular basis. This post is about how I built a Coffee Pot Monitor, to track the coffee level in a coffee pot, remotely, using a Load Cell, HX711 amplifier, and a Raspberry Pi.
Imagine yourself being busy with something important. You take a quick break to grab some coffee and walk over to the break room only to find an empty coffee pot.
There’s no way for me to know the amount of coffee left in the pot, without walking over to the break room and checking it out. The coffee pots we have at work are opaque. So, it’s not possible to know the amount of coffee left in the pot by looking at it.
