[arm-allstar] pcsensor ---solution

One more quick question, what would be the proper process to tweak the temperatures it pulls from the device for calibration purposes? For instance, say the usb device is reading 5 degrees hotter than another reputable thermometer in the same physical location, and I want to calibrate the usb device to read the same temp as my other thermometer by decreasing it's output by 5 degrees.

Hi Dusty,

I ordered one of the PC TEMPer2 sensors from Amazon and got it last Friday.  I was unable to find a query program for this exact device after goog'ling around for a while, so I wrote a simple brute-force tool, based on earlier code.  Please give this solution a try, to make sure it works with your sensor.  To install, go to a bash prompt (admin menu #9) and install with pacman, like:

pacman -Sy hamvoip-sensors

The program for this exact model is named: temper2_V3.7  ...With the
TEMPer2 sensor plugged into the RPi, run this command and you should see output similar to:

root at david-ryzen9:/export/rpi/# temper2_V3.7 
DATE|VERSION|TEMP1C|TEMP1F|TEMP2C|TEMP2F|HIDDEV
2021-12-03-04:12:10|TEMPer2_V3.7|24.43|75.97|19.81|67.65|/dev/hidraw5

The output is a CSV style layout, using "pipe" ('|' vertical bars) characters as the field delimiters.  The software is a simple bash script, at this point (see the file: /usr/local/sbin/temper2_V3.7), so modification, as needed, is easy.


Merry Christmas and Happy Holidays!
