KC868-A16 board - wired security system
#6
Hi,

I am interested in a similar project.
I am running a Domoticz-based home-made alarm for a long time, using Rasberry Pi GPIOs to connect door/window reed sensors and trigger the alarm sound/light, and I want to update/extend it, so I would like to switch to a A16 board and Home Assistant.

At that time, I had to build a DIY Rasberry Pi HAT to filter out transient spikes that appeared on the sensor lines:

   

Are the A16 inputs more immune to spikes and EMI than the RPi ? Or do you think I must also precondition the signal by adding RC filters ?

Also, what is the power consumption of the A16 board (not counting MOSFET outputs of course), so that I can choose the right 12V power supply.

Kind regards,

Vincent
