💡 What is a solid state relay used for in DIY temperature control and automation projects?

In practice, it lets you switch higher voltage/current loads from a low-voltage control signal. - Handy for heaters, fans, or motors controlled by microcontrollers or PLCs
- Provides isolation to protect control electronics and reduce noise
- Helps maintain stable temperatures by precise on/off control
- Works with a selectable input voltage range (3-32V) and output range (5-200V)
