Description

The LC1BD04 module provides a fundamental solution for digital liquid level sensing. It utilizes conductive or resistive sensing probes (not included) at four distinct points, with internal comparators converting the presence or absence of liquid into clean digital logic signals. This design eliminates analog signal conditioning requirements, offering a straightforward interface for system integration.

Engineered for reliability in benign environments, the module is intended for use with non-corrosive liquids. Its compact form factor and soldering-terminal interface make it suitable for embedded installation within enclosures, water tanks, humidifiers, and reservoir control systems, providing a cost-effective method for basic level monitoring and alarm functions.

Key Features

  • Multi-Point Digital Sensing: Provides four independent digital outputs corresponding to distinct liquid level thresholds.
  • 5V Logic Compatibility: Designed for seamless integration with 5V microcontrollers (Arduino, etc.) and digital logic circuits.
  • Direct-Solder Interface: Features robust soldering pads for permanent, vibration-resistant wire connections, ideal for fixed installations.
  • Compact PCB Construction: Small footprint allows for flexible placement within tight control panels or device housings.
  • Low-Power Operation: Consumes minimal current, making it suitable for battery-backed or energy-conscious monitoring systems.
  • Simplified System Design: Digital outputs reduce software complexity compared to analog sensors, requiring only GPIO reading.

Applications

  • Residential and commercial water tank level control and low-level alarm systems.
  • Automated top-up control for humidifiers, aquariums, and hydroponic nutrient reservoirs.
  • Liquid level monitoring in DIY electronics projects and prototyping platforms.
  • Simple pump control logic in small-scale irrigation or drainage systems.
  • Educational demonstrations for digital sensing and basic automation principles.

Frequently Asked Questions

What is the operating voltage range for the LC1BD04 module?

The module is designed for a nominal 5V DC supply. While it may tolerate slight variations typical of regulated microcontroller power rails (e.g., 4.75V to 5.25V), operation outside this range is not recommended as it can affect the digital output signal integrity and comparator reference levels.

How do I connect sensing probes to this module?

The module provides soldering pads for connection. You must solder wires from each of the four level detection input points to your conductive probes or sensor electrodes. A common ground/reference probe is also required. The module itself outputs a digital signal; the external probes form the sensing element.

Can this sensor be used with liquids other than water?

It is suitable for non-corrosive, non-conductive liquids where the liquid itself acts as a resistive path to complete a circuit. For conductive liquids (like saltwater) or corrosive chemicals, the simple probe design may be unsuitable due to electrolysis, corrosion, or short-circuiting, potentially damaging the module or providing false readings.

What microcontroller platforms is this module compatible with?

The digital outputs are directly compatible with any 5V logic microcontroller, such as most Arduino boards (Uno, Mega), ESP32 (with 5V tolerance or level shifter), and 5V PLC digital inputs. For 3.3V systems (like Raspberry Pi, STM32), a simple voltage divider or logic level converter is recommended to protect the lower-voltage GPIO pins.
