DC 3V-5V Water Level Sensor

A simple analog sensor for detecting water presence and checking basic water levels. It works by sensing conductivity across exposed traces on the board. Features: Operating voltage: DC 3V–5V Analog signal output Detects water level and water droplets Detection area: about 40 × 16 mm Low operating current Compact PCB design Easy to use with Arduino and similar boards Applications: Water level alarms Rain detection projects Tank level monitoring Overflow warning systems Arduino school projects DIY automation
