SMS Based Pump Controller with Automatic Dry Run Shut Off

Last Updated on June 11, 2026 by Swagatam 22 Comments

irrigation system

In this post I will show how to construct a SMS based water pump controller with automatic shutdown of pump when no water flow through the pump is detected.  We will also construct another much simpler automatic dry run preventer circuit without GSM in the next half of the article. What is Dry Run in […]
