how to use water level sensor by ESP32 board & automatic control relay

[@محمدرزق-ح1ح]

Thank you for your effort. I have identified the mistake, which is connecting the water level sensor to point A4. I have connected it to point A1 instead, and the readings change as the level changes. Thank you.

thanks for video. can we use digital level sensors insted? I want to make a auto water change system. For example, for one day a week, the drain pump operates up to the low level sensor. Then it stops and the filling pump runs up to the upper level sensor. Is such a somewhat complicated scenario possible with this interface?

sure, you can chose water float switch sensor. just detect HIGH or LOW level.

Does it record data as the depth of the water increases or decreases? Is it possible to measure the inflow or outflow of this water with this equipment?

[@KinCony]

this is a sensor, whether data record according to your MCU's software code.

will this automation work without internet? You will make the automation with internet, after if you disconnect the internet, will the set automation and analog-digital input-output still work?

[@KinCony]

sure , must work without internet. it's important. logical automatic control locally without network

[@qintiy]

can you do the same but with esphome and homeassistant

[@KinCony]

later will do that, config by esphome with ADC.

That'd be great, thanks!
