Water Sensor WS2 For Home Assistant By SCREEK (wifi, esp32-c3, esphome)

One of the many great suggestions we received after WS1 was to support multiple levels of probing, which became kind of a nagging issue for us, as connecting multiple probes to a single controller can dramatically reduce costs, as well as reduce redundant controllers, and also allow signals to be processed at once, which has a lot of benefits. Even in terms of power energy is more economical.

We've been testing and designing for a long time, we've been testing our prototype for probably over three weeks as of now at the time of release, and we're on a humidifier, over and over again, to make sure that everything's working okay.

Yes, it's working okay.

Now we've received feedback from the first users of the WS1, and they're getting good work out of it in faraway lands.

So we are now sharing with you our latest water level sensor, the WS2, which has some new features:

Although manufacturers advertise sensors as very powerful and seemingly omnipotent. But in our idea and application, we applied it to a humidifier with no water level detection and it worked quite well. Also a thickness like 10mm seemed to respond well in our basic tests.

I guess the fascinating thing about this sensor is that it doesn't have to touch the liquid to detect it, which enables some interesting uses.

As with all SCRREK sensors, it's just a few simple steps to access the Home Assistant.

From now on, you will be able to know all the time whether the water level sensor detects the water level or not and use this information for some interesting automation.

Sensors are based on the principle of capacitive detection and suffer from the problem of sometimes being too sensitive or not sensitive enough.

From the sensor documentation:

- If the non-contact level sensor does not detect or the detected level deviates from the sensor distance, the
Setting method. - Use small objects (such as pens, toothpicks) to click the sensitivity button, the LED indicator begins to flash, the sensor begins to automatically adjust the sensitivity. 3-5 seconds, the flashing stops, the LED indicator lights up, the automatic adjustment is complete, to achieve the most suitable sensitivity required by the current position.
- Note: The position to be detected must have liquid, not empty, otherwise the setting is invalid.

The main characteristics are derived from the sensor's introductory information.
