The Module Operates by detecting changes in the capacitance of liquids to determine the liquid level height or thepresence of liquid.

Product Features:

①Small size, low cost

②No mechanical movement, no wear and tea

③Non-contact, better sealing and safety

④Capable of detecting multiple types of liquids: water, alcohol, cooking oil, etc.

Module Specifications:

①Module PCB Size: 37mm x 12mm

②External Power Supply and Water Level SignalTerminal Hole Spacing: 2.54mm(can connect wires, pinheaders, or other 2.54mm spacing terminals based onapplication needs)

③ Port Definitions (refer to PCB markings):

* OUT:Water level signal output (low level for waterpresence, high level for no water)

* －: Connect to power supply negative

* + :Connect to power supply positive; operatingvoltage range: 3.0V-6.0V

③Usage Requirements: This module has no definedsensing PAD, it can be chosen based on actual applicationneeds, such as copper film, springs, etc.5)PCB Design: Includes reverse polarity protection.

Application：

①Intelligent floor scrubber, sweeping robot

②Water purifier, water dispenser, direct drinking machine

③Coffee machine, juicer

④Alcohol meter

⑤Chemical material containers or other liquid containers
