PCSensor / TEMPer2 driver for Linux/Solaris 
====

![TEMPer](images/New_TEMPer_6.jpg)

A CLI tool for PCsensor TEMPer USB thermometer. http://www.pcsensor.com/

This is based on PCSensor v. 1.0.1 by Juan Carlos Perez, introduced at https://relavak.wordpress.com/2009/10/17/temper-temperature-sensor-linux-driver/

Support device 0c45:7401 known as Gold TEMPer. (image above)

I have worked on, 
- Change libusb-0.1 -> libusb-1.0 (to be able to build on Solaris)
- Support multiple devices
- Add Munin plugin http://munin-monitoring.org/
- Some code cleanups, fix indents, typos, ...

# Build
## Solaris 11
```
# pkg install gcc libusb-1
$ make
...
# cp pcsensor /usr/local/bin/
```

## RHEL 6
```
# yum install gcc libusb1-devel
$ make
...
# cp pcsensor /usr/local/bin/
```

# Usage
```
$ sudo ./pcsensor
2017/08/31 19:00:35
Temperature (0:internal) 81.28F 27.38C
Temperature (0:external) 214.60F 101.45C
2017/08/31 19:00:35
Temperature (1:internal) 81.16F 27.31C
Temperature (1:external) 214.60F 101.45C
...
```

libusb_detach_kernel_driver does not seem to work on Solaris. Thus, it looks necessary to unload hid driver manually.
Are there any better solutions? (See pcsensor.sh)

PCSensor / TEMPer2 driver for linux

This is based on PCSensor v. 1.0.1 by Juan Carlos Perez

All I've done is tweak the tool to output both the temperature from the internal
as well as the external sensor.
