I’m planning an automated garden watering sensor with a submersible pump and a Sonoff S20 socket
My question is whether there’s a solution to the tank water level issue -
I plan to put the water pump inside a large-enough water tank, but then there’s the question of how much water is left in the tank
I thought about an ESP8266-based project but couldn’t find anything useful/simple enough to start with
Float switches are the simplest, they will give a contact closure at a set level.
Then there’s resistive strips that change resistance depending on the water pressing on the (insulated) envelope up the side of the tank.
There are also pressure sensors that work on the water pressure on the submersed open end of a sealed tube (the top is sealed the bottom is open and there’s air trapped inside that gets pushed on and compressed as the water rises).
Then there are ultrasonic transducers that measure the travel time of sound to the water surface and output either a digital or proportional signal.
Can you please share what you’ve done to reach this goal ? I’m pretty new to these kind of things (familiar with ESPEasy and the like) and could use any hand you can lend me here
Any of the mentioned options can be included into HA very easily with ESPhomeyaml. Search for it on this forum. I’m on my phone so it’s a little hard right now to give you a link
I’m using the LevelPro Sentinel Remote tank level monitoring device for a long time without any trouble and also the support team is very helpful. You can also measure the level remotely. So you can check this device from Icon Process Controls website: https://iconprocon.com/product/sentinel-remote-tank-monitoring/
