Temperature and Humidity Sensor Node Design

I’ll create a 5 V Omron G2RL relay driver board using an MMBT2222A low-side transistor, add the required coil flyback protection and connectors, then run a schematic check.
I found a 5 V Omron G2RL variant in the library plus the requested MMBT2222A; I’m adding a 5 V/control input, relay contact terminal, base resistor, base pulldown, and flyback diode now.
Processing was stopped.
Here's a summary of what I was working on: Inspecting pin details
I'm thinking I need to infer the G2RL-1A pin connections. There are coil pins—maybe 1 and 8? And for the contacts, it seems like 3 could be COM, while maybe 4 is NO, but I’m uncertain about pin 6. I want to check the pin descriptions to be sure about all of this, so I’ll take a closer look. It’s important to get these details right to avoid any mistakes!
3.3V input drive
Add screw terminals
Add driver protection
Set board size
@copilot Ho bisogno di pilotare questo relè omron g2rl 5v. Aggiungi un transistor NPN BC817, una resistenza da 1kΩ per la base e un diodo di flyback (come l'1N4148) per proteggere il circuito dai picchi di tensione
