Benewake TFmini-S Problems and Solutions

Here are some common issues and problems with the Benewake TFmini-S lidar, along with solutions suggested by experts:

Issue: The lidar does not work properly if the line sequence is connected wrong.

Solution: Make sure that the TX and RX lines are connected correctly. You can check the line sequence on the lidar's external terminal. Do not unplug the junction between the lidar and the cable, and pull out the cable to see the line sequence. This will cause irreparable damage to the product.

Issue: The lidar does not detect liquids.

Solution: This is because the lidar uses light as a medium of detection. When detecting liquids, there will be transmission, which will seriously affect the ranging performance.

Issue: The lidar's performance is affected by ambient light (sunlight).

Solution: The lidar works best at night (without artificial lights). During the day, the performance of the lidar is affected by the intensity of the ambient light and the signal. The stronger the ambient light, the weaker the lidar signal, and the worse the performance of the lidar (increased error).

Issue: The lidar does not need a protective cover for outdoor applications.

Solution: The lidar is designed with IP65 rating, and can work normally under normal outdoor conditions. However, if you need to use it in heavy rain, a protective cover is needed to improve the protection grade.

Issue: The lidar's output cannot be changed to 8 bytes.

Solution: The TFmini-S does not support 8 bytes output. If you need to convert the serial data into CAN network data, you can purchase a TLL/CAN adapter board on the official Benewake website.
