Description

The Seeed Studio RS485 Ultrasonic Level Sensor is a high-precision, non-contact distance measurement module designed for demanding industrial environments. Utilizing high-frequency sound waves, this sensor calculates the distance to target surfaces with a measurement range of 25cm to 500cm. Unlike mechanical level sensors, its ultrasonic technology prevents fouling and corrosion by remaining entirely separated from the measured medium. With a robust IP67 rating and internal temperature compensation algorithms, it ensures consistent data delivery despite shifting environmental conditions and ambient noise.

Industrial Precision & Stability

Robust All-Weather Design Fully sealed IP67 enclosure allows for permanent outdoor installation in wet, dusty, or humid conditions without compromising the transducer.
Standardized Integration Communicates via RS485 using the Modbus RTU protocol, enabling direct connectivity to PLCs, industrial controllers, and IoT gateways.

Professional Monitoring Scenarios

Liquid Level Tracking: Monitor water reservoirs, tanks, and chemical vats without contacting the liquid.
Smart Waste Management: Identify fill levels in urban trash bins to optimize municipal collection logistics.
Parking & Proximity: Detect vehicle presence and manage horizontal distances in automated industrial processes.
