What is the main purpose of using a relay module with a Raspberry Pi in home automation?
easy🧠 Conceptual Q11 of 15
Step-by-Step Solution
Solution:
Step 1: Understand relay module function
A relay module acts as a switch controlled by the Raspberry Pi's GPIO pins to turn devices ON or OFF safely.Step 2: Identify the purpose in home automation
It allows the Pi to control high-power devices without directly handling high voltage or current.Final Answer:
To safely control high-power devices using low-power GPIO signals -> Option BQuick Check:
Relay modules = safe device control [OK]
Quick Trick: Relays switch big power with small signals [OK]
Common Mistakes:
MISTAKES- Thinking relay speeds up the Pi
- Confusing relay with data storage
- Assuming relay provides network access
