Hello,
I have a water tank to harvest rain water used for my toilets and washing machine.
I wanted to have a visual display and the info in my HA to save me opening the cover.
So I started buying some stuff to start with my project:
- esp8266
- ultrasonic HC-SR04 sensor
- ssd1306 oled display
- sht40 temp and humidity sensor
- 3d printed housing for my ultrasonic sensor
some pictures of the WIP:
The code is used:

My current challenge is being able to convert the water tank height into liter.
My tank looks like this:
Can anynody help with the formula to calculate the volume knowing the diameter and lenght of the tank and the height of the water?
Thank you!
