Description:

The module operates by detecting changes in the capacitance of liguids to determine the liquid level height or thepresence of liquid.

Product Features:

*Small size, low cost.

*No mechanical movement, no wear and tear.

* Non-contact, better sealing and safety.

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

Module Specifications:

①Module PCB Size: 32mm x12mm

②External Power Supply and Water Level SignalTerminal Hole Spacing: 2.54mm(can connect wirespinheaders, 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.

Application：

*Intelligent floor scrubber, sweeping robot.

*Water purifier, water dispenser, direct drinking machine.

*Coffee machine, juicer.

*Alcohol meter.

*Chemical material containers or other liquid containers.
