Microcontroller Unit detects different dielectric constant of the nonmetal glass or acrylic vessel and liquid, then alarm the Hi or Low liquid level.

LED color indicates the Hi or Low liquid level.

Universal power supply (100～240VAC).

Design for reducing wave interference.

Easy to install the sensor by adhesive tape or strapped wire.
