Description

The Seeed Studio RS485 Ultrasonic Level Sensor is an industrial-standard solution for non-contact spatial measurement and liquid level monitoring. Utilizing high-frequency ultrasonic waves, this sensor calculates the distance to a target based on Time-of-Flight (ToF) principles, covering a vast range up to 750cm (7.5 meters). Designed for reliability in harsh environments, it features internal temperature compensation to maintain accuracy despite thermal fluctuations. Its ruggedized IP67 housing makes it impervious to dust and water, while the industry-standard RS485 interface ensures seamless data collection for smart city, agricultural, and industrial automation networks.

Precision Non-Contact Sensing

Robust IP67 Waterproofing The sensor is fully protected against immersion, making it suitable for outdoor use in sewers, flood monitoring, and open water tanks.

Advanced Signal Processing Features integrated algorithms for interference suppression and stable data output via Modbus RTU RS485.

Industrial Monitoring Scenarios

• Liquid Level Monitoring: Real-time tracking of water tanks, reservoirs, and chemical containers without probe contact.

• Smart Waste Management: Monitor fill levels in public trash bins and containers to optimize collection routes.

• Flood Early Warning: Deploy in rivers and drainage channels to monitor water rising during extreme weather events.
