Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

Arduino-based water level detector with LED indicators and buzzer alerts. Uses a capacitive sensor for real-time monitoring of tanks/reservoirs. Compact, open-source design ideal for STEM/DIY projects ...

This project is a smart water level controller built using Arduino UNO, an ultrasonic sensor, and EEPROM for memory storage. The system automatically monitors the water level in a tank and controls ...

The circuit is infact a dark activated switch measures the ambient light level and will enable the system only when ambient light level is below a threshold value. Here an LDR (Light Dependent ...
