Hello, I just want to know if the lmsensors package can damage the system and the computer ? I just ran the sensorsdetect command. Thanks.

I have heard of no one reporting damage to the computer. The disclaimer is there just to make you aware of potential risk. I believe all the recent motherboards and cpu are fine with it.

I have heard of no problems, even when confirming "yes" when lm_sensors discourages it. But there is a little risk left.

The command itself cannot harm your computer - it just reads data from the different sensors.

(Only scenario that I can image where damage can occur is if you use the data to control your fan for example. If the data you read is not correct, you may overheat your PC (usually BIOS shuts it down to prevent damage))

From the man page: sensors-detect needs to access the hardware for most of the chip detections. By definition, it doesn't know which chips are there before it manages to identify them. This means that it can access chips in a way these chips do not like, causing problems ranging from SMBus lockup to permanent hardware damage (a rare case, thankfully.)
