Solid State Contactor Circuit for Motor Pumps

electronic solid state contactor circuit

In this article we learn how to design and build a solid state contactor circuit using triacs for operating heavy duty loads like submersible borewell pump motors with high reliability, and without any concerns about wear and tear issue or long term degradation issues of the contactor unit. What is a Contactor A contactor is … Read moreSolid State Contactor Circuit for Motor Pumps

SMS Based Pump Controller with Automatic Dry Run Shut Off

In this post we are going 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 Motors … Read moreSMS Based Pump Controller with Automatic Dry Run Shut Off

Automatic Irrigation Circuit using Arduino

In this post we are going to construct an automated water irrigation system for small garden using arduino and soil moisture sensor. Introduction The proposed system can monitor the soil moisture level and when soil moisture goes below preset value, the 12V DC pump will be triggered for predetermined period of time. The status of … Read moreAutomatic Irrigation Circuit using Arduino
