I would just use the exec plugin (https://collectd.org/wiki/index.php/Plugin:Exec) for something like this.

Basically you need to decide if it is a counter, gauge or derivative, then adjust the output.

  echo "PUTVAL \”${hostname}/sensor-${instance}/gauge-${label}\" interval=$COLLECTD_INTERVAL N:${recorded_value}”

do you know what the value data is? 25600 seems a high input temperature. What is the scale?
