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 tear

③Non-contact, better sealing and safety

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

Module Specifications:

①Module PCB Size: 30mm x15mm

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

③ Port Definitions (refer to PCB markings):

0: 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

④Usage requirement: Designed for containers with flatsurfaces, with the sensing surface required to maintaindirect contact with the container during operation.

⑤PCB Design: There is no reverse connectionprotection on PCB, the power supply positive andnegative poles should not be reversed, otherwise it iseasy to burn out.

⑥lmportant Reminder : This module has no definedsensing PAD; it can be chosen based on actual applicationneeds, such as copper film, springs, etc.

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
