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

Description: IntroOne 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:Supports up to four probes, (not compatible with WS1 probes now because of the change in wire sequence.)Same great non-contact probing capability of up to 15mm as WS1, (still does not penetrate metal).💡The following documents are mainly from WS1, some of them may be outdated and we will try to improve them as soon as possible. Instructions for useAlthough 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.Plug in the USB power (Type-C powered) and let it boot up.Wait for about 10 seconds or so and a hotspot will appear, "Waster-Sensor WS2", connect to this hotspot, select your network, enter your password and click confirm.Now Home Assistant on the same network will automatically discover the device.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.Calibration sensorsSensors 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, theSetting 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.SpecificationsSize: Control(44mm x 28mm x 11mm), Single Probe(about 34mm x 24mm)Max Probes: 4Power supply: Type-C power supply, 5V 1A.
