SemLab CLS-24BP Contactless Liquid Level Sensor Module - 5V to 24V, Capacitive Non-Contact Liquid Detection, NPN/PNP Output

The SemLab CLS-24BP Contactless Liquid Level Sensor Module is a capacitive, non-invasive liquid detection solution designed to detect the presence of liquid through non-metallic container walls without direct contact with the fluid. By using capacitive sensing technology, the module can detect liquids through materials such as plastic, glass and acrylic, helping prevent sensor corrosion, contamination and degradation caused by direct exposure to liquids or chemicals.The module operates from a wide 5V to 24V DC supply and provides a selectable NPN or PNP-style output, making it suitable for interfacing with PLC inputs, relays, microcontrollers and automation systems. It features an onboard sensitivity adjustment potentiometer and LED status indicator for convenient calibration. With a sensing capability through container walls up to 20 mm thick, the SemLab CLS-24BP is suitable for liquid presence detection, tank monitoring, industrial automation, chemical applications, agricultural systems and IoT projects.Features:Non-contact capacitive liquid level detectionDetects liquid through non-metallic container wallsWide 5V–24V DC operating voltageSupports selectable NPN and PNP output modesUp to 20 mm container-wall sensing capabilityStated liquid level accuracy of ±1.5 mmFast response time of ≤800 msUp to 100 mA output drive capabilityBuilt-in sensitivity adjustment potentiometerOnboard LED for detection/status indication4-pin header interface for easy connectionCompatible with PLCs, relays, Arduino, ESP32 and other controllersOpen-source hardware and firmwareSuitable for industrial automation, IoT, agriculture and chemical applicationsSpecifications:ParameterSpecificationModelSemLab CLS-24BPSensing TechnologyCapacitive, non-contactOperating VoltageDC 5V–24VStandby CurrentApprox. 5 mAMaximum Wall ThicknessUp to 20 mmAccuracy±1.5 mmResponse Time≤800 msOutput TypeOpen-collector transistorOutput ModeNPN / PNP selectableOutput DriveUp to 100 mAInterface4-pin headerSensitivity AdjustmentOnboard 10kΩ trimpotStatus IndicatorLEDMCUWCH CH32V003F4U6Protection RatingBare PCB / IP00Sensing MethodThrough container wallRecommended ContainersGlass, plastic, acrylic and other non-conductive materialsPinout :PinLabelFunction1VIN5–24V DC Power Input2MODEFloating = NPN / GND = PNP3OUTLiquid Detection Output4GNDGroundFor more information checkout : Contactless Liquid Level Sensor Module Wiki PagePackage Includes:1 × SemLab CLS-24BP Contactless Liquid Level Sensor Module
