Add relative humidity sensor #258

Closed stillwer closed 5 years ago

stillwer commented 5 years ago

Scott would like to add the ability to measure the relative humidity within the MPD containers. Add control to track this like other housekeeping data.

Omega humidity sensor never came with a power chord. Servers Check sensors did and are alive and working.

stillwer commented 5 years ago

In order to read the Servers Check humidity sensor, I am using simple network management protocol (SNMP). The object identifiers that are needed to read the sensor can be found using the file SERVERSCHECK-MIB.txt. If you navigate to the location of that file and use the command line command: snmptranslate -Tz -m ./SERVERSCHECK-MIB.txt It will dump all the object identifiers in the file.

Note that the directions for the linux based commands were here: https://www.linuxquestions.org/questions/programming-9/how-to-get-oids-form-a-mib-file-4175428161/

The OID's that are important are:

"sensor1Value" "1.3.6.1.4.1.17095.3.2" "sensor3Value" "1.3.6.1.4.1.17095.3.10" "sensor4Value" "1.3.6.1.4.1.17095.3.14" "sensor5Value" "1.3.6.1.4.1.17095.3.18"

They are the Internal Temp 1, External Temp, Relative Humidity, and Dew Point Temperature. Those names can be found by using:

"sensor1name" "1.3.6.1.4.1.17095.3.1" "sensor3name" "1.3.6.1.4.1.17095.3.9" "sensor4name" "1.3.6.1.4.1.17095.3.13" "sensor5name" "1.3.6.1.4.1.17095.3.17"

Default ip address is: 192.168.11.160. Reset it to be 192.168.0.170. Will plan to do this for all subsequent hardware.

Pushed the tester into the repo this morning.

stillwer commented 5 years ago

Also pushed the test code into the structure needed to run within the container and within the template.

stillwer commented 5 years ago

Just put the humidity sensor on a book instead of the metal floor of the container and it is dramatically increasing the temperatures and also reducing the RH and dew point.

This seems to be done. Currently testing on MPD 4 but the start looks promising. Will close this and enter any other issues as bugs as they arise.
