+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
+
+which uses https://github.com/dpavlin/mq7-co-monitor/
+
+on Arduino to produce output which is then fed to dsm501.pl.
+
+
+Another strage one is audio2influx.sh which doesn't require
+any external hardware but instead report sox info about 1s
+or audio to influxdb. I'm using this to passivly monitor
+fan rotation by connecting it directly to microphone input
+on netbook and adjusting input gain to prevent clipping
+using alsamixer.
+
+To make alsamixer work, I had to remove pulseaudio.
