Water Level Sensor Readings Not Changing with Water Level Variations - engmohades - 10-29-2023
Hello, I have a KC868-E16S board and installed the firmware KCS V2.1.9 on it. I connected a water level sensor that operates in the range of 0 to 5 volts and 0 to 0.7 meters.
I tested the sensor by placing it in a water tank with an actual height of 41 cm.
I noticed that the sensor reads up to 35 cm and the reading seems to remain constant even when the water level increases or decreases. For example, when I lowered the water level to 15 cm, the sensor did not register the change and the reading remained at 35 cm.
Similarly, when I increased the water level to 42 cm, the sensor reading did not change.
Can you help me solve this problem?

what software you will use? for example : home asisstant? or you just want make a AUTOMATION to control relay?

First, I want to create an automation to control a relay without software , and then I will use Tuya software later

Hello, is there any update regarding the problem's solution?

preparing one sensor with 70CM , then will begin test, when have news i will upload at here.

i use KC868-E16T for testing, but KC868-E16S is same. connect water level sensor with analog input1.
because the water level sensor output signal is dc 0-5v. level range is 0--70cm
CHA1 and CHA2 use for 0-5v. CHA3 and CHA4 use for 4-20mA
i use pump later water full of bottle.
the big bottle concave about 2-3 cm.
when the water level is 46cm. i test with software and multi meter as follows:
when i change water level from 0-46cm, webpage will auto update the value. i think you need to confirm whether you have use analog 0-5v port?
later i will take a video tour about water level testing.

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.
Thank you very much. Now everything is working fine.
