PIR sensor behind glass?

Nususu

@cowboysdude I recently picked up these microwave sensor modules to use in conjunction with the code you posted for PIR Sensor. I’m pretty new to all this, and I can’t get any function out of the sensor. Do you have some advice on how to troubleshoot this? It could be an error on my part in implementing the code, wiring it incorrectly, or something else, but I’m just not sure how to figure out what the issue is.

cowboysdude

@Nususu I would go online and lookup ‘wiring pir sensor raspberry pi’ there are TONS of things out there. Your issue could be one of any or a combination of things… I did that using a PIR sensor so I have no idea how it would act with microwave sensors… good I’m hoping because I want to get some… BUT let me know if you need anymore help, not that I helped you now but I will do what I can!

@cowboysdude thanks, I’ll check that out and let you know how it goes!

@cowboysdude I got it working using this code:

https://github.com/paviro/MMM-PIR-Sensor

With this code, I’ve got a problem where the screen only stays on for about 1 second after motion detection. Now I need to modify the code somehow to allow me to tell the mirror to stay on for a set amount of time after detecting motion, i.e. only go dark once no motion has been detected for x seconds. Problem is I don’t know where to start with that. Will let you know if I figure anything out. Any ideas?

@Nususu try adding the powerSaving to your config…

{
        module: 'MMM-PIR-Sensor',
        config: {
            powerSaving: false
        }
    }

See what that does :) PLUS there’s also an adjustment on your PIR sensor itself… which one and I don’t know … do a google search for adjustments :)

@Nususu - same here

Perhaps, with a resistor?

Nususu

@Aly I found documentation for the sensor that a resistor would indeed solve the issue here. I can set the delay up to 200 seconds with a 250k resistor, so I ordered one and will report back how it went.

Aly

@Nususu - great !!

Can you post the doc. ?

Nususu

@Aly I misspoke, shouldn’t have called it documentation. Rather, it was this picture: alt text

Which appears to be a translation from the Chinese original picture.
