The highest measuring accuracy is ±0.3m when sensor measures in 5 to 300m. If measuring range is further than 300m, the measuring accuracy of sensor is ±1m.

Then sensor will emit a laser beam and prepare for working, and return the data "FF 00 0A 0A 0A 00" to the serial interface. 4.2.2.2 Send a command "O" (ASCII) or "0X4F" (HEX) again to the sensor to start to measure distance. The sensor will return the measured data like "FF XX XX XX XX XX" to the serial interface and turn off laser beam when it finished one time measurement. For example, if measured distance is 123.4m, computer will receive data like "FF 00 01 02 03 04". 4.2.2.3 Send a command "U" (ASCII) or "0X55" (HEX) to turn off the sensor. 4.2.3 Continuous Measuring Mode 4.2.3.1 Send a command "O" (ASCII) or "0X4F" (HEX) by computer to turn on the sensor. Then the sensor will turn on the laser and prepare for working, and return the data "FF 00 0A 0A 0A 00" to the serial interface 4.2.3.2 Send a command "C" (ASCII) or "0X43" (HEX) to the sensor. The sensor will begin to measure continuously after 3 seconds when it got the order, and return the data continuously like "FF XX XX XX XX XX". If the sensor couldn't get any available data, it will return "FF 00 0A 0A 0A 00" to the serial interface. 4.2.3.3 Send a command "U" (ASCII) or "0X55" (HEX) to turn off the whole sensor (include both of laser unit and measuring unit). -4- 5.

Its measuring range and accuracy will be effect by many external environmental factors. So actual measuring result might be different with typical value which is measured in standard environment. The following factors will effect actual measuring range: Effect Factors Increase measuring range Decrease measuring range Surface of target Bright and smooth surface with good reflection, like target plate Deep color and rough surface, like green or blue target surface Air visibility Clean air Dust, fog, storm and rain, snow Ambient light Dark environment Target exposure to strong light, like sunlight in midday Laser emission Laser emission lens and protection glass keep clean and smooth Laser emission lens and protection glass get dirty or scratched In conclusion, the best measuring result will be happen in a dark environment and with a good reflection target. We strongly suggest to use a target plate when laser distance sensor works in a poor environment. We also suggest to keep laser emission lens and protection glass clean with a soft cloth before start to using. -6- 6.2 Error code display Laser distance sensor user manual All error code are either displayed with "FF AA 00 XX XX XX". The following errors can be corrected.
