RS485 (MAX485) Non-Contact Ultrasonic Water Level Sensor — 3m Range, DC 5V, IP65

Designed for continuous, low-maintenance water level monitoring, this non-contact ultrasonic sensor delivers accurate measurements up to 3 meters. It communicates via RS485 with MAX485 Modbus protocol output for straightforward integration into existing control and monitoring systems. The unit runs on DC 5V and is energy-efficient, drawing less than 20mA during normal operation and dropping below 1mA in sleep mode for long-term deployment. Built to withstand harsh conditions, the sensor is rated IP65 and operates reliably across a wide temperature span of -20°C to +70°C. Simple to install and operate, it offers dependable performance for a variety of industrial and environmental applications.
