Reliable and compact
Small form factor makes it easy to hide in my enclosure. The digital output makes coding very simple. Highly recommend for hobbyists.

Solid performance
Works as expected for water levels. Note that it does not work through metal containers, which is stated in the description, but worth remembering.

Perfect for my aquarium automation
This sensor works exactly as described. I mounted it outside my plastic tank and it detects the water level accurately without any holes drilled. Very happy with the purchase.

Great for non-contact projects
I used this for a chemical project where I couldn't touch the liquid. It works through the plastic bottle perfectly. Easy to interface with my ESP32.

Good sensitivity but needs tuning
The module works well but I had to adjust the potentiometer to get the right sensitivity for my specific container thickness. Once set, it is stable.
Q: Is this compatible with Arduino Uno?
A: Yes, the module operates at 3.3V to 5V DC and provides a digital TTL output, making it fully compatible with Arduino Uno and similar boards.
Q: How do I adjust the detection sensitivity?
A: There is a small potentiometer on the module board. Use a screwdriver to turn it clockwise or counter-clockwise while testing with your liquid.
Q: Will this sensor work through a metal tank?
A: No, this capacitive sensor requires non-metallic containers such as plastic or glass to detect the liquid level effectively.
Q: Can it detect liquids other than water?
A: Yes, it can detect most non-corrosive liquids including oil and chemicals, provided the container material is non-metallic.
Q: What is the maximum container wall thickness?
A: It typically works well with wall thicknesses up to 10mm, but this may vary depending on the liquid and container material.
