Multiple lights dimming using single TRIAC zero detcetion module

Question

We know well we can dim single lights using single TRIAC module with the help of PWM signals from controller. My question is, I want to control the lights which are placed on hall. Let us consider 15-20 bulbs.

1. Is it possible to control single PWM signal and single TRAIC module?
2. We need to consider only current value of TRIAC module?
3. What are all the hardware points should be consider at the time of automate.
4. Which micro-controller is best for home automation?
5. Is it possible to ON/OFF lights using TRIAC module? If its not how to do that?

Answer 1

1. Is it possible to control single PWM signal and single TRAIC module?

Figure 1. TRIAC dimming uses phase-angle control.

Yes, but we use phase angle control, not PWM.

2. We need to consider only current value of TRIAC module?

It is unclear what you are asking.

3. What are all the hardware points should be consider at the time of automate.

You write the user requirements, not us.

4. Which micro-controller is best for home automation?

This is impossible to answer as you have no requirements.

5. Is it possible to ON/OFF lights using TRIAC module?

Yes. Zero trigger delay will give full power. No trigger will give zero power.
