Hello! is there any solution to maintain the level of sensitivity after switching off and on the sensor or the arduino?can someone help me please?

The description is misleading and all the schematic is misleading and labels are missing
JaneYu Dunno if you ever got sorted Rakshit, but capacitance sensors do not work through metal. You need a sonar based sensor for LPG.
JaneYu I tried the sensor with a 10mm glass ( aquarium) and it always finds water even if there isn’t. I tried all 4 levels of sensitivity. It works fine with thinner glass. I tried putting a sheet of paper between the sensor and the glass, but still no good. The spec says 13mm. Does anybody have any ideas how to overcome it?
JaneYu Question about sensitivity adjustment for liquid sensor XKC-Y25-T12V. There is a button on the gravity interface board and also a potentiometer on the sensor itself. What does the button actually do to adjust the sensitivity?
For that matter, what does the gravity interface boad do? Is it needed? If I give the sensor 5V I'll get 5V back. What's its purpose?
JaneYu Hello, good morning. My name is Tamara.
i wanna ask about non liquid level sensor. What the solution about the level can't be function. Can you help me or the solution? Thankyou
JaneYu Hi Team, I have conformed to the documentation, Added rubber padding between the sensor and metallic container but still the sensor always shows that liquid is present; even for an empty container. Very BAD EXPERIENCE with this sensor. I have attached a photo of the setup. https://uploads.disquscdn.c...
JaneYu Don't the specs of the sensor say that it won't work for metallic containers, non-metallic only?
Or do you have any sensor which would help me do that?
JaneYu use weight sensor
Is this sensor safe for fish and other animals if used on an aquarium?
Also from other comments, this is a capacitance based sensor, correct?
JaneYu Hello,
Can it be used for measuring grains such as rice in a storage bin (silo)?. It is a proximity capacitive sensor? TQVM
JaneYu Hello,
I came across many varieties of this sensor like XKC-Y25-T12V, XKC-Y25-V, XKC-Y25-PNP, XKC-Y25-NPN, can someone please let me know the differences. Few have sensitivity settings through trimpot in the sensor plastic body and XKC-Y25-T12V has no trimpot but have an adaptor PCB with tactile switch to set the sensitivity level. Please clarify..
JaneYu Hey,
Is there also a sensor to measure the distance from the water to the container?
That it is possible to measure how full the container is (in cm).
Because I conclude from this that it is only possible to measure higher or lower than the point of the sensor.
Thank you
JaneYu Hey,
A simple solution for this is to use a ultrasonic range sensor at the top of your container and this sensor will relay this distance values between the top of the container and the water level. You can find this product here: https://www.dfrobot.com/pro...
Hi I want to put 2 sensors on this bottom and top of tank to turn on and to turn off and it needs to turn on 900watt pump will it do this and can you please simply say all components so I can buy with many thanks
JaneYu Can I use this for measuring under water at a swimming pool I want to build a system that can detect when you go under 75cm under water ? thx
JaneYu Hello, We have been using these liquid level sensors in one of our coffee machine products for a few months now. We have about 100 units working with clients. We are using the sensors to detect the presence of water in a thin walled (1mm nom.) plastic tank. Until recently they have been working fine. However we are starting to see sensors that will no longer detect the water correctly. Bizarly if one puts ones finger in the water in the tank the sensor will again detect the water until ones finger is removed.Why has this changed, nothing about the machine has changed and the water is straight from the tap or from bottles and has not changed since the day the machines were installed.The sensor is currently acting as a simple switch sending a high or low signal to our PIC proceesor. If we fit a new sensor the function returns to normal. It would appear that the replaced sensors sensitivity is somehow reduced.We had intended to use these sensors in many other products but we are now nervous about migrating them into new products if the life is so short.
We understand that it is possible for the sensitivity of the sensor to be adjusted by pressing the small button on the PCB that comes with the sensor. Pressing the button has never seemed to make any difference to the sensitivity at all. How may one determine what the sensitivity level is set to? Also how may we set the sensitivity to maximum in new equipment as the clients do not have access to the button, we could send some pulses to the sensor whenever the machine is switched on if this would be a solution?
We would be pleased to hear your advice about this as there is very little imformation available for this sensor .
Thank you.
JaneYu Does anybody know the part number for the 4 pin connector on the interface board?
JaneYu Hello,
raspberry Pi newbie: The liquid level sensor xkc-y25-t12v, can it be used with the raspberry pi? what about software?
JaneYu Hey! I have used this sensor with the pi 3 B+ and can confirm it is working but the sensor itself doesn't seem worthwhile itself. I couldn't make it work on metallic surfaces even after following the documentation.
