Checks temperature and humidity using a Watchport Environmental sensor.
This plugin checks the temperature or humidity from a watchport sensor.

The temperature and humidity checks are in separate files.

Parameters :
-w - warning threshold
-c - critical threshold
-p - device port, default it /dev/ttyUSB0

Add the nagios user to the 'dialout' group to allow access to the serial port.

When I first made this, I had issues with the USB sensor locking up after every read. To get around this, I made a version to reset the USB device after every read. See the github page for this version: https://github.com/nsafran1217/check_watchport
I added an ACL to the USB device file to allow nagios write access. I added a udev rule so this ACL is added when the device is plugged in.
Example, you will have to change the identifiers:
SUBSYSTEM=="usb", ATTRS{idProduct}=="0305", ATTRS{serial}=="V72983794-0", ACTION=="add", RUN+="/bin/setfacl -m u:nagios:rw- /dev/$name"
