40m 2mm Precision laser distance sensors range finder TTL Uart Serial port module Ardunio

 Precision laser distance sensors 2mm ranging range finder Uart Serial port module 

Datesheet

Technical Parameters:

Measuring range: 0.045-D (D is the maximum range) currently module D = 40, D = 70, D = 80, D = 100, and other specifications

Resolution: 0.01 mm (0.00001 m)

Measurement accuracy (standard deviation): ± 2.mm (within 10 m).More than 10m the formula is ± 2 + 0.05 * (D-10), D is the distance

Distance Unit: meter

Laser Type: 620-690nm

Laser Class: Ⅱ grade, <1mW (secondary safety)

Single measurement time: 0.25s

Spot diameter: 6mm @ 10m,

Working temperature: -0 ~ + 40 ℃

Storage temperature: -20 ~ + 60 ℃

Weight: 60g

Dimensions (length × width × thickness): 4.8cmX3.7cmX1.8cm

Supply voltage: DC3v-3.3v

IO voltage: TTL level compatible 3v-5v voltage

Use item indoor without reflectors, when use black target at close range also can be ranging, for example, the surface of black leather purse,

please use reflectors fit, If item return non-reflective within range of outdoor.

Note:

** In harsh environments such as: the sun is too strong, the ambient temperature fluctuations, the reflecting surface is relatively weak effect, system voltage is too high or too low, if the measure distance is close, the result may be a larger error, recommend using a target plate in this situation .

** Prohibited beyond the marked electrical range when using module, using non-compliant power supply voltage may damage the module.

**5v IO connected directly pls set to driving, if use the AVR or STC microcontroller, please Series connection 1KΩ current-limiting resistance.

Communication Interface:

The module uses the TTL serial port for data exchange, communication rates up to 115K (baud rate 115200)

Just open the laser, but does not measure, can be used for targeting (the laser turned off automatically after the timeout)

Apparent size and interface: 

Matters needing attention:

User banning or welding to open the module this module on any device,

Prohibition of module to look directly at the Sun

The module contact liquid

Using alcohol or organic solvents to clean the lens

Use or other objects directly to clean lens

Rated voltage other than supply voltage
