100m 2mm Precision laser distance sensors range finder TTL Uart Serial port module Ardunio

Description

Technical Parameters: Measuring range: 0.045-100m Resolution: 0.01 mm (0.00001 m) Measurement accuracy (standard deviation): ± 2.mm (within 10m ); ± 6.5mm (more than 10m)  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.
