Circuit Documentation

Summary

This circuit is designed to control a 5V mini water pump using a relay module and an IR sensor. The relay module is powered by a 5V battery, while the water pump is powered by a 9V battery. The IR sensor detects an object and triggers the relay, which in turn activates the water pump.
