I'm quite new to actual physical "engineering" and I am just getting started.
My current project is to build a light switch, which triggers my room light via wifi.
I have two cables in my wall (like this) which - when connected - trigger a relais in my flats fuse box which switches the light. The two wires run on ~16V, and when connected have a short spike of current of about 4-8mA. This spike lasts for about a second and drops to 0 afterwards.
So my plan is to use this SSR with an ESP-01 3.3V (which has a maximum current of 12mA per pin, so that should be enough), wire up the two cables and the esp-01 with the SSR and let the ssr switch the light.
So a few questions:
- Is there something obvious I missed? I'm still a beginner and trying to make sense of all these information, so there might be something I missed.
- If I read the datasheet right, I need 10mA@6V to trigger the SSR, is that right? How can I map this to 3.3V? And what does RL under conditions @ minimum trigger conditions mean? Is this a resistance I put before the Pin?
Concerning the Pin-layout of the module: I guess the pins 1,3 & 4 are the ground pins for my ESP-01, a load on pin 2 triggers the optocoppler. I'm not quite sure about the pins on the AC side. What are the Pins T1, T2 and Gate for?
Thanks in advance for your help!
