APPLICATION CONSIDERATIONS：

1: This module should not be connected with power. If you want to have a live connection, let the

Gnd terminal of the module be connected first. Otherwise it will affect the module work.

2: When measuring distance, the area of the object to be measured is not less than 0.5 square

meters and should be as flat as possible. Otherwise it will affect the test results.
