RS485 500cm Ultrasonic Level Sensor

The RS485 500cm Ultrasonic Level Sensor offers 1mm resolution and IP67 protection for reliable distance measurement. With RS485 communication and LoRaWAN® compatibility, it’s ideal for precise, long-range monitoring in challenging environments.

The RS485 500cm Ultrasonic Level Sensor uses ultrasonic technology for precise distance measurement, offering a range from 25cm to 500cm with 1mm resolution. Its IP67-rated waterproof transducer ensures reliable operation even in harsh environments. This high-precision, low-power sensor is ideal for accurate level and distance monitoring. It supports RS485 serial communication, allowing easy integration with other devices. It’s also compatible with the SenseCAP LoRaWAN® Data Logger, enabling connection to a LoRaWAN® network for long-range, low-power data transmission. Configuration and firmware updates can be carried out using the included serial port tools. Features
