@@ -12,3 +12,16 @@ network latency to influxdb (which is somewhere in the cloud, and
 latency can vary just enough to create empty vertical stripes in
 graphs which is ugly and incorrect).

+Exception to that rule is dsm501.pl which is general serial to
+influx bridge used by helper shell scripts to handle sensors
+which require 5V by connecting them to Arduino-like mcu.
+Example of that is:

+mq7.sh
