Seeed LL-RS485 Liquid Level Sensor

Seeed Liquid Level 0.5 - 4.5V IoT Sensor. The Seeed Liquid Level IoT Sensor measures the height of water or other liquids and converts it to voltage signal. It works with a data logger or other devices that have analog voltage input ports.

Note: This is not a RS485 Sensor, it is a device puts out a Variable voltage based on depth

The Liquid Level Sensor has a built-in silicon piezoresistive core that features high sensitivity. The internal chip converts the millivolt signal into a standard voltage signal, which can be connected to a computer, control instrument, or PLC.

It's small-size and lightweight makes it easy to install. With a sealed stainless steel probe, it can work in water, oil, and mild-corrosive environments. The sensor has high anti-vibration and anti-impact performance. It can be widely used in process control, aviation, aerospace, automobile, agriculture, Viticulture, Horticulture and other IoT applications.
