20m L Shape Little LiDAR Sensor RxD TxD
This LiDAR measurement sensors has already been widely used in many industrial-grade applications but at a competitive price. The laser distance measurement module is good for high-class design. The Little LiDAR Sensor supports continuous measurement function, so that customers can use to monitor the distance change(20m distance).
Advantages：
Miniature-sized: 31mm for height, 17mm width, 20mm thickness
Easy to install: 90 degree design
It will be useful if you reply us. Some Parts description is as follows.
Model No.: U85L02-20m(b211019) for example
Baud Rates: 19200bps
Size: 31*17*20mm
Distance: 0.03-20m
Applications: robots etc.
Best Regard
Key parameters:
1. Reliable, fast, precise
Three interfaces optional: ttl, usb, rs232
Accuracy: +-1mm
Measuring time: 0.4s-4s
2.Small, long range
Size: 31*17*20mm for 90 degree
Measuring range up to 20 m
U81 U85 laser working principle
The optical distance sensors achieve 10m short-range presence detection using a visible, focused laser beam spot. According to the latest version, customers can test the laser range components simply via using all available distance functions commond of the hexadecimal system. High resolution up to 1mm, the arduino distance measurement laser usually used to some samrt monitoring project.
Detailed parameters
Range: 0.03 meters - 20 meter
Visible measuring: 620nm ~ 690nm
Measuring accuracy: +-1 mm
Measuring frequency: Up to 3 Hz
Laser type: Class 2, red
Interface options: Serial/usb/rs232/rs485/bluetooth
Size: 41*17*7mm
Working temperature: 0 ~ 40 degree
Storage temperature: -25 ~ 60 degree
Notes:
1. Under bad measure condition, like environment with strong light or the diffuse reflectance of measuring point over-high or low, the accuracy would have bigger amount of error: ±1 mm+40PPM.
2. Under strong light or bad diffuse reflectance of target, please use a reflector.
3. Voltage can be changed by power converter LDO
4. Frequency would be affected by environment.
5. Operating temperature -10 ℃~50 ℃ can be customized.
6. Analog can be customized.
