PCSensor / TEMPer driver for Linux/Solaris
|
|
====
|
|
|
|
A CLI tool for PCsensor TEMPer USB thermometer. http://www.pcsensor.com/
|
|
|
|
This is based on PCSensor v1.0.1 by Juan Carlos Perez, introduced at https://relavak.wordpress.com/2009/10/17/temper-temperature-sensor-linux-driver/
|
|
|
|
Supported devices:
|
|
- 0c45:7401 with 1 temperature sensor (Gold TEMPer)
|
|
- Tested with TEMPerV1.4
|
|
|
|
|
|
|
|
- 0c45:7401 with 2 temperature sensors (TEMPer2)
|
|
- Tested with TEMPer2_M12_V1.3
|
|
|
|
|
|
|
|
- 0c45:7402 with temperature and humidity sensors (TEMPerHUM)
|
|
- Tested with TEMPer1F_H1_V1.4
|
|
|
|
|
|
|
|
I have worked on,
|
|
- Change libusb-0.1 -> libusb-1.0 (to be able to build on Solaris)
|
|
- Support TEMperHUM
|
|
- 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/
|
|
```
|
|
## Ubuntu 16 & 18 / Debian
|
|
```
|
|
# sudo apt install libgusb-dev gcc
|
|
# make
|
|
...
|
|
# cp pcsensor /usr/local/bin/
|
|
```
|
|
|
|
# Usage
|
|
```
|
|
$ sudo ./pcsensor
|
|
2017-09-26T20:49:24 0 temperature 31.69 C
|
|
2017-09-26T20:49:24 1 temperature 32.12 C
|
|
2017-09-26T20:49:24 2 temperature 33.44 C
|
|
2017-09-26T20:49:24 2 humidity 62.63 %
|
|
...
|
|
```
|
|
|
|
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)
|
|
|
|
(Added on 2018-11-24)
|
|
It has been tested on Solaris 11.3 and libusb-1.0.20, and looked working fine.
|
|
On Solaris 11.4, libusb-1.0.21 was introduced. But, pcsensor doesn't seem to work with 1.0.21.
|
|
I found it can work with libusb-1.0.21-rc2, but cannot work with libusb-1.0.21-rc3 or above.
|
|
If you would like to use it on Solaris 11.4, get libusb-1.0.21-rc2 from github and install it.

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.
