RS485 Ultrasonic Ranging Sensor (35~550cm)

Introduction

What is an ultrasonic distance sensor?

Our ultrasonic distance sensor is a ranging directional sensor equipped with an IC chip. The distance from the sensor to an obstacle can be calculated by the time difference between sending an ultrasonic signal and receiving that reflected sound. Ultrasonic sensors are widely applied to various industries and robot control areas, and offer convenient control and high efficiency in real time data feedback.

RS485 waterproof sonar range finder from DFRobot is an ultrasonic distance sensor designed for professional industry controls and robotic controls. The sensor is equipped with distance and temperature measurement functions. Additionaly, the built-in temperature compensation greatly enhances the accuracy of distance measurement.

The internal elements of the sensor are completely sealed. The sensor adopts all metal outer case, which makes it able to protect against dust, water and corrosion. In the end the sensor has high standard device selections, a much narrower blind area and wider distance detection range.

RS485 employs RS485 communication interface, and supports modbus protocol and cascaded control functions. This ultrasonic distance sensor is very suitable for a liquid level monitoring system or obstacle avoidance applications
