60m Green Laser Measure Distance Sensors Arduino

Short Description:

BA9D green laser distance sensor is a special new generation of measuring equipment, using 520nm green laser band, with short wavelength but more energy, clear green light, wider measurement range, and can be seen clearly in backlight or even dark environments.

Measuring Range : 0.03~60m

                 Accuracy : +/-3mm

              Laser Type : 520nm, >1mW, Green Light

                      Output : RS485 interface

Green laser distance has strong penetrability and can be used in liquid and underwater engineering projects. The green laser measure can also measure the distance of the red high-temperature solution. Due to the difference in the color of the light source, the repetitive color interference can be effectively avoided, so as to achieve effective distance measurement.

Product Introduction

The green laser measure distance sensor is a green laser measuring device that continuously measures distance online (all-day online measurement) and can transmit data in real time. According to this feature, the distance sensors arduino can be used for industrial monitoring, industrial intelligent automation, security alarm systems, etc. The human eye is 4 to 5 times more sensitive to green light than red light, so it is better to use green light laser distance sensor in complex environments.

High accuracy distance sensor arduino is a non-contact industrial measurement technology. Compared with traditional contact ranging technology, it has the following characteristics:

(1). When laser measure, there is no need to contact the measurement surface, and the surface of the object will not be deformed.
(2). The surface of the object to be measured will not be worn during laser ranging, reducing additional damage.
(3). In many special environments, there is no condition to use conventional measurement tools for contact measurement, and only laser ranging technology can be used.

2. High Accuracy Laser Distance Transducer
1. Distance Transducer
3. High Precision Distance Sensor


1.Can a laser distance sensor detect clear glass?
The laser sensor is based on the principle of optical detection. The laser will pass through the transparent glass, resulting in a certain probability of missed detection. We suggest that when using it for scenes with glass, you can add some auxiliary reflection methods, such as pasting frosted stickers, or with other non-optical sensors as a supplement.

2.Are Laser Rangefinder Sensors Harmful to Eyes?
Seakeda's long distance sensor arduino adopts class I and class II laser eye safety standards, and its laser intensity is small to cause damage to the eyes. Of course, we still recommend not to look directly at the laser distance sensor at a short distance for a long time, and try to avoid placing it at the same height as the human eye level plane during installation.
