Turck IM18-CCM50 Ambient_read

README.md

This flow executes a script included on a Turck IM18-CCM50. The script is called ambient_read.sh and outputs the value of the onboard temperature and humidity sensor of the Turck IM18-CCM50 module. This flow executes the script every 30 seconds (this can be changed after importing) and converts the output of the script to a JSON object.
