Optimus Water Level Indicator DIY Kit Price in Sri Lanka

The Water Level Sensor DIY Kit is an easy-to-build electronic project designed to detect and indicate water levels in tanks, reservoirs, and containers. Using a simple transistor-based sensing method, the kit detects water at different levels and activates corresponding LED indicators to visually display the tank status.

The circuit operates by utilizing the conductivity of water to trigger BC547 NPN transistors, allowing the LEDs to illuminate progressively as the water level rises. When the tank reaches the full level, an onboard buzzer is activated to provide an audible alert. This hands-on project is ideal for learning basic electronics, transistor switching, and sensor-based circuits while offering a practical real-world application.
