1. Overview

Laser ranging sensors are mainly used to measure objects with a fixed or moving speed of less than 1 meter/s. Its main characteristics:

(1) Can maintain high accuracy and reliability even in harsh environments.

(2) The working voltage range is large (7-30V), and it can be powered by car power supply, industrial switch power supply, ordinary DC power supply, etc.

(3) Low power consumption, 0.2W in standby mode 0.3W, 1.0W during continuous operation 1.5W.

(4) The measuring laser is a visible laser, aiming at the object being measured.

(5) Communication interface RS485

(6) Analog and switch quantities can be programmed through commands, making them flexible to use.

(7) Flexible operation, can be performed by sending commands through PCs, microcontrollers, etc., or through external trigger lines.

(8) Remote control can be achieved by adding wireless modules.

2. Safety Notice

This series of laser ranging sensors has a maximum laser emission power of 1mW and a safety level of 2. If an accident occurs and the human eye is exposed to laser light for a short period of time (greater than 0.25 seconds), the human eye can be protected by the blink reflex of its own eyelids. The blink reflex of a person can effectively protect their eyes. Although the product may not require specialized safety protection devices, it is still necessary to avoid direct viewing of the laser beam as much as possible. Do not aim the laser beam directly at the human body. Sensors can be used without any protective measures. Application precautions:

(1) When sunlight or other strong light directly enters the sensor lens, errors may occur.

(2) Measuring objects with poor reflective surfaces in strongly reflective environments may result in errors.

(3) When the reflection surface of the object being measured is too strong, measurement errors may occur.

(4) Measurement through transparent objects such as glass, filters, resins, etc. may result in incorrect data.

(5) When rapidly changing the measurement environment or measuring distance, the sensor may return no data or generate incorrect data for a short period of time.

(6) The measurement rate indicated by the sensor is the static measurement rate, which will slow down when measuring the speed of dynamic objects. The laser sensor supports a speed of 1m/s, and it is recommended to use it when the speed is less than 0.5m/s.

3. Working principle

This series of laser ranging sensors uses the principle of phase comparison for measurement. Laser sensors emit visible laser beams of different frequencies, receive scattered laser light returned from the measured object, compare the received laser signal with a reference signal, and finally, use a microprocessor to calculate the distance between objects corresponding to the corresponding phase shift, which can achieve millimeter level measurement accuracy.
