Topic: How to measure level of sand in a bucket/tank (Read 141 times) previous topic - next topic

I need to remotely determine the level of sand in a tank.

Once the sand levels in the tank are low, I want to receive a notification or turn an LED on (so to remind me to refill it).

I was wondering if there were sensors out there that could help me with this.

One idea I had was to have a proximity sensor attached to the lid of the tank that would point straight down to measure the height of the sand pile (once it reached half the tank height I would turn an LED on).

This is probably a bad way to do this and I want to implement a more elegant/accurate system.

Help/advice would be appreciated!
