The module test is a tool developed to test the module builds of the Ultrasonic Time-of-Flight (ToF) sensor product line and for engineering development purposes. It is an autonomous test that checks the functionality and performance of ToF sensors. Its test methods include the following features:
• Checks sensor functionality after the assembly process
• Checks and displays sensor performance data against product specifications and criteria.
• Records sensors data log for traceability and data analysis
• Distinguish different types of failures for binning.
