An Automatic Solution for Efficient Water Management


Water is a precious resource, and its efficient management is crucial. Traditional methods of filling water tanks often lead to water wastage due to overflow or inefficient filling. The Smart Water Level Controller is designed to tackle these issues by automating the water filling process, ensuring that your tank is neither underfilled nor overflowing.

How It Works

The Smart Water Level Controller uses conductivity-based sensing to monitor water levels in the tank. It employs two level indicators connected to a power-switching relay, which in turn controls the water pump. When the water level is low, the system activates the pump. Once the water reaches the high-level mark, the system deactivates the pump, preventing overflow.

Key Features

  • Automatic Operation: The auto water level controller takes over the task of switching the water pump on and off, making the process hassle-free.
  • Energy Efficient: By automating the pump’s operation, the device helps in conserving electricity.
  • Cost-Effective: With a competitive water level controller price, this device is a budget-friendly solution for water management.
  • Versatile: The water level controller for 3-phase motors is also available, making it adaptable for various applications.
  • Easy Installation: The water level controller PCB kit comes with all the necessary components for a straightforward setup.

Circuit Diagram and Working

The water level controller circuit diagram consists of a 555 Timer IC, water level sensor, and relay. The low and high-level sensors are placed at their respective positions in the tank. When the water level is low, the circuit triggers the low-level LED and activates the relay to turn on the water pump. Once the water reaches the high level, the high-level indicator LED turns on, and the relay switches off the pump.
