I’m looking to track the current tank capacity of a bedroom humidifier with a small smart scale so that I know when it is close to being empty. I’ve seen projects that do this for larger out-of-sight weights (propane tanks, etc.), but I was wondering if you had any suggestions for smaller loads while in sight (the scale is not ugly).
The pressure membrane looks elegant but has a low weight capacity (max 1kg). I’m guessing my humidifier has a capacity of a gallon which would put it well over weight.
The micro load cell looks more durable and should handle the weight. Would that sensor be in a general kitchen scale like this one? I could then yank the guts and hook it together with an ESP32 module to do constant measurements. Is this what you were referring to, @potts-mike? A link to some similar project instructions would be very helpful if anyone has created them.
