Thermal Sensor

Deadline
1

Hi
I would like to create my own thermal sensor base on Arduino.
It is an open-source electronics prototyping hardware and software.

I need to now how deadline is communicating with the sensor.
I now it’s on port 161. Could you give me other informations?

regards
Lucas

Hey Lucas,

Deadline communicates with the sensor using SNMP:
en.wikipedia.org/wiki/Simple_Net … t_Protocol

We build the request packet based on the IP, oid, and community values specified in the sensor configuration, and we parse the response for the value.

Cheers,

Thank’s Ryan for all these informations.

I setup my sensor.
This is what get from Net-Snmp with the command:“snmpget -v 1 -c public 192.168.1.64 1.3.6.1.3.2009.0.3.0”
SNMPv2-SMI::experimental.2009.0.3.0 = INTEGER: 20

20 is the correct value for my temp…

But in “add thermal sensor windows” when i click on test i get this:

Could not query sensor because:
SNMP: Response is not of type Integer, it is of type 0 (System.Exception)

Should i send an output that is a string with a particular syntax or anything else?

cheers Lucas

Sounds like the type byte isn’t being set properly. According to the SNMP standard, the type byte for integer is 0x02, but that byte in the response you’re getting is 0x00.
