100m high precision laser sensor 2mm range finder module serial port module for Obstacle warning distance measurement

 100m high precision laser ranging sensor deviation 2mm range finder module serial port module distance measurement

Outdoor lightIn combination with special reflectors more than 20 meters.

VCC 3.3V 5V must be burned, is the current increases, the phenomenon is chip fever)

Using the PC software can easily get the error status of the module, such as measuring distance too tight, measured movements too quickly, or there is no reflection, reflection, such as various error messages,

Objects blocking the laser or lens, you can simulate the fourth error

On the front of the module, one or two centimetres in the block, you can simulate the first error,

As long as the module can return data, response data, indicates the module is OK,

Range when operating current, 120mAIf the laser is not working laser failure

Avalanche driver 110V, if the receiver part of the bad, you are prompted to receive failure

Currently both a hard error, if no data is mostly lines connection problem or software problem, you can try to reset

About precision, you can use the continuous distance measurement mode static measurement, accuracy can look the screenshot below

Parameters:

Measuring range: 0.05-40 m 

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

Distance unit: m

Laser type: 620-690nm

Laser class: class ⅱ, <1mW (B-level security)

Single measurement time: 0.25-1S

Spot diameter at the distance m: 6mm@10m,30mm@50

Operating temperature: -10~+60 c

Storage temperature: -20~+80 c

Weight: about 60g

Dimensions (length x width xThick):4.8cmX3.7cmX1.8cm

Power supply voltage: DC3v-3.3v

IO Voltage:TTL Level compatible 3v-5v Voltage

**In harsh environments such as:Sunlight is too strong,Ambient temperature fluctuations are too big,Relatively weak reflector,System voltage high/low,Measuring distance is near,The result could be greater errors,Recommended to use with the target in this case reflector**

**Modules use the prohibition beyond the marked electrical range,Does not meet the required supply voltage can damage module,

5v IO Directly set to drive,If AVR Or STC Single-chip microcomputer,List of series 1K Ohm resistor**

Communication interface:

Module communication speeds up to 115k(115200) And can connect to the high-speed system, functional instructions as follows

1. Opens the laser only, but does not measure,Can be used to target(Laser opens automatically after a timeout to close)

2. Single measurement

3. the continuous measurement of

4. Stop measuring

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
