High-precision laser distance measurement sensor module uses light measurement, so all working ideas should follow the characteristics of light, such as light reflection, penetration and other characteristics.

The phased laser ranging sensor measures statically at the white wall of 3 meters indoors, with an accuracy of ± 1mm, a maximum rate of 20Hz (TTL interface, 485 and the fastest 10Hz of analog current interface), and a range of up to 80 meters (the reflection point needs to be equipped with a reflector).

Shortening the range does not lead to an increase in accuracy; The data rate returned by different interfaces will vary. TTL >> 232>> 485>> 4-20mA analog current interface.

*(1) With a strong reflector, it can measure a longer distance. The range value can be set by means of a downstream command up to 80 meters.

*(2) In bad environments, such as outdoor sunlight, the performance will be affected, and it can be used with the target reflector to improve the performance.

*(3) In fast mode, the recovered light signal is weak, and the error will become larger, which has certain requirements for the measurement target and distance.

*(4) Not suitable for outdoor daytime applications.
