The LCT-1 Liquid Level Controller DIY Kit is an excellent project for enthusiasts, students, and engineers who want to build an efficient water level management system. It provides precise monitoring of water levels with automatic control over water pumps or solenoid valves. This versatile kit is perfect for water tanks, aquariums, irrigation, or industrial applications.

Parameters

Kit Name: Liquid Level Controller

Model: LCT-1

Operating Voltage: 5V

Relay Contact Capacity: 3A/250V

Control Board Size: 45mm x 71mm

Sensor Size: 86mm x 24mm

The LCT-1 Liquid Level Controller offers two operation modes that can be switched using button S1. It provides precise water level control with clear LED indicators for different water levels:

• Red LED: Low water level
• Yellow LED: Medium water level
• Green LED: High water level

Operation Modes

• Automatic Water Filling Mode:
• • When the water level is low (red LED), the relay is activated, turning on the external water pump to start filling.
  • Once the water reaches a high level (green LED), the relay switches off, stopping the water pump.
  • As the water level drops back to the low level, the relay reactivates, and the process repeats.
  • Application: This mode is used in automatic water-filling systems to maintain the water level between the low and high thresholds.

• Automatic Water Draining Mode:

  • When the water reaches a high level (green LED), the relay activates, turning on the external solenoid valve to start draining the water.
  • Once the water level drops to a low level (red LED), the relay turns off, stopping the solenoid valve.
  • When the water rises back to a high level, the relay reactivates, and the process repeats.
  • Application: This mode is ideal for automatic drainage systems, ensuring the water level stays between the low and high thresholds.

This kit provides a reliable, easy-to-use solution for managing water levels in water tanks, aquariums, or industrial water systems, ensuring efficient water management with minimal user intervention.
