Seeed Studio S-LL-01A Liquid Level Sensor | 314990619

The Liquid Level Sensor accurately measures the height of water or other liquids and converts it into a voltage signal, compatible with data loggers or devices featuring analog voltage input ports. Equipped with a built-in silicon piezoresistive core, it offers high sensitivity and converts millivolt signals into standard voltage signals, facilitating connection to computers, control instruments, or PLCs.

Compact and lightweight, the sensor is easy to install and features a sealed stainless steel probe suitable for water, oil, and mild-corrosive environments. With high anti-vibration and anti-impact performance, it finds applications in process control, aviation, aerospace, automobile, medical equipment, HVAC, and more.
