Yes, the unit needs to be calibrated. This is very easy to do.
You aim the sensor at the sun and adjust the small potentiometer visible through the hole in the front panel using a jewellers screw driver until the reference voltage is 1V.
Here are a couple of links with great detail on how to make one & how it works.

So far, we have found it very useful.
nobody seems to remember building has been discussed in detail on SolarChat already in 2015 viewtopic.php?p=197225&hilit=ssm+build#p197225
Good to see my software is still usefull.
I see the Linux version, what software are you using for capturing? (If FC, you can steer captures from the plugin)
BTW, nice captures you made.
Paul
Thank you for your software! It saved us the issue of writing something of our own to capture the data from the SSM.
Yes, we are aware of the previous thread re the SSM and software on Solar Chat.
We just thought from the responses to our thread that there were a number of people who were not aware, so it wouldn't hurt to include other relevant links.
Yes, we do run the software on Linux. Another thank you for having a Linux version of your software
No, we don't use FC. We use ZWO's own ASICAP for capturing.
The reason for this is that with no amount of adjusting environment variables have we been able to make FC capture as fast as the ZWO software. We have even gone to the point of downloading the ZWO SDK and working through some examples and compiling them to try to get to the bottom of the issue. We stopped doing this when a friend of ours, who works as a Linux developer, tried everything that he could, including custom kernels to try to fix the data transfer rate with FC on Linux and failed. He has done a lot more than us using not only ZWO cameras but QHY & PlayerOne as well. In the end, very reluctantly he has given up and bought and uses a Windows notebook running FC for capturing.
So we do not use the SSM to trigger capturing, rather we waited until the average line was trending down and then took a series of videos and then selected the best one.
Thanks again
